1. Field of the Invention
The present invention relates to an apparatus and method for manufacturing a consumable candy drinking straw.
2. Background of the Invention
Candy is typically a single function and single use product. A consumer generally buys a candy product for the sole purpose of consuming the candy. There are various forms of candy, including hard candy, typically manufactured primarily from sugar and flavoring, chocolate, soft candy, etc. Hard candy having a chocolate or flavored center is known. Regardless of its type, the candy typically is consumed by itself when the candy is placed in the mouth of a consumer.
Fruit flavored beverages, sometimes called “smoothies,” have recently become popular. A typical smoothie has finely ground ice particles combined with flavoring. Frequently, finely ground fruit is the flavoring in a smoothie. Due to its thick consistency, the smoothie typically is consumed with a straw or sometimes a straw that also functions as a spoon. The spoon or straw usually is made from plastic and allows the consumer to suck the smoothie from the cup or receptacle holding it.
Because the straw is formed of plastic, it imparts no flavor to the smoothie and merely allows the smoothie to be withdrawn from the receptacle. There thus exists a need for a mechanism to alter and/or augment the smoothie's flavor.
In addition, there is a need for a candy product that can be used for purposes other than simply consumption. There is also a need for creative and fun candy products that have some utility other than their flavor.
The present invention provides a method of manufacturing a candy drinking straw. The method includes arranging a soft mass of sugar composition around a solid mold having a support cord extending from an end thereof, rolling the sugar composition along a surface of the solid mold using a plurality of rotating scrolls rotating around the solid mold to shape the sugar composition into a hollow tube, the sugar composition being pushed along the solid mold onto the support cord, pulling the sugar composition along the support cord to form hollow cylindrical candy, and cutting the hollow cylindrical candy into a plurality of hollow candy segments.
The soft mass of sugar composition may be produced from liquefied sugar and glucose syrup. Before arranging the soft mass of sugar composition on the solid mold, a plurality of soft masses of sugar compositions of different colors and different flavors may be combined into a single mass of sugar composition.
After pulling the sugar composition along the support cord to form hollow cylindrical candy, the hollow cylindrical candy may be twisted with respect to the support cord to form swirled candy stripes on the candy. The twisting of the hollow cylindrical candy may be performed by transferring the hollow cylindrical candy on the support cord between a plurality of rotating belt units arranged opposite to one another each rotating in different directions to apply different forces to the candy such that the candy is twisted with respect to the support cord.
The hollow cylindrical candy may be removed from an end of the support cord before cutting the candy.
The support cord may have a diameter that corresponds to an inner diameter of the candy drinking straw. For example, the diameter of the support cord may be about 5 millimeters.
The solid mold may have a conical shape with the support cord extending from a smaller bore of the solid conical mold. Additionally, the support cord may be bound inside the solid mold at a first end thereof and extends inside along a length of the solid mold out of a second end thereof.
The pulling of the sugar composition along the support cord may be performed by moving the sugar composition along a movement track defined by a plurality of rollers that apply a rotational pressure to move and pull the sugar composition along the support cord. In addition, the sugar composition may be pulled along the support cord to form a hollow cylindrical candy having an outer diameter of about 12 millimeters and a thickness of about 3.5 millimeters.
The present invention also provides a candy drinking straw manufacturing apparatus to manufacture a candy drinking straw. The manufacturing apparatus includes a scrolling unit to receive a solid mold having a soft mass of sugar composition arranged therearound. The scrolling unit includes a plurality of scrolls rotating around the solid mold to shape the sugar composition into a hollow tube and to push the sugar composition along the solid mold onto a support cord extending from an end of the solid mold. The apparatus further includes a pulling unit to pull the sugar composition along the support cord to form hollow cylindrical candy and a cutting unit to cut the hollow cylindrical candy into a plurality of hollow candy segments.
The soft mass of sugar composition may be made from liquefied sugar and glucose syrup. The soft mass of sugar composition may include a plurality of soft masses of sugar compositions of different colors and different flavors.
The manufacturing apparatus may further include a twisting unit to receive the hollow cylindrical candy from the pulling unit and to twist the hollow cylindrical candy with respect to the support cord to form swirled candy stripes on the candy. The twisting unit includes a plurality of rotating belt units arranged opposite to one another each rotating in different directions to apply different forces to the hollow cylindrical candy to twist the candy with respect to the support cord when the candy is transferred between the rotating belt units.
An end of the support cord may be arranged between the pulling unit and the cutting unit such that the hollow cylindrical candy is removed from the support cord prior to cutting. The support cord may have a diameter that corresponds to an inner diameter of the candy drinking straw, for example, about 5 millimeters.
The solid mold may have a conical shape with the support cord extending from a small bore of the solid conical mold. The support cord may be bound inside the solid mold at a first end thereof and extends inside along a length of the solid mold out of a second end thereof.
The pulling unit may include a plurality of rollers arranged in two parallel lines defining a movement track therebetween. The rollers apply a rotational pressure to move and pull the sugar composition along the support cord disposed in the movement track. The pulling unit may pull the sugar composition along the support cord to form a hollow cylindrical candy having an outer diameter of about 12 millimeters and a thickness of about 3.5 millimeters.
The present invention also provides another candy drinking straw manufacturing apparatus to manufacture a candy drinking straw. The manufacturing apparatus includes a scrolling unit having a rotating support member around which a soft candy mass is arranged. The rotating support member has a first end disposed in the scrolling unit and a second end extending out of the scrolling unit and is rotated and pressed by the scrolling unit to gradually decrease a diameter of the soft candy mass from the first end toward the second end of the rotating support member. The apparatus further includes a pulling unit to pull the sugar composition along the rotating support member to form hollow cylindrical candy, and a cutting unit to cut the hollow cylindrical candy into a plurality of hollow candy segments. The rotating support member may include a conical portion disposed in the scrolling unit and a cylindrical portion extending from the conical portion out of the scrolling unit into the pulling unit.
The present invention further provides a candy scrolling apparatus. The candy scrolling apparatus includes a housing, a plurality of scrolls disposed in the housing along a length thereof, the scrolls being rotatable with respect to the housing and defining a recess extending along the length of the housing, a conical mold disposed in the recess and extending along the length of the housing to be rotated by rotational forces received from the scrolls, and a support cord extending from a smaller end of the conical mold out of the housing.
The candy scrolling apparatus further includes a soft sugar composition mass arranged around the conical mold being rotated and molded by the scrolls such that the soft sugar composition mass is transferred along a surface of the conical mold to a surface of the support cord by forces applied by the rotating scrolls. The soft sugar composition mass may be formed into a hollow cylindrical shape around the support cord when the scrolls are rotated.
The support cord may be made of plastic.
The present invention further provides a candy mold usable to form a candy drinking straw. The candy mold includes an elongated conical portion having a small end and a large end, and an elongated cylindrical portion extending from the small end of the conical portion. The candy mold is insertable in a scrolling machine having a plurality of rotating scrolls to gradually roll a candy mass around the conical portion onto the cylindrical portion to shape the candy mass into a tubular candy cylinder.
The candy drinking straw 1 can enhance the flavor of whatever beverage is being enjoyed by a consumer. The candy drinking straw 1 maintains a stable solid state and is only relatively slowly dissolved from within by the beverage being transported therein and by the saliva from the mouth of the user. On the other hand, a consumer's saliva may dissolve an outer portion of the candy drinking straw 1 to add flavor to the beverage being consumed. Once the consumer finishes the beverage, the candy drinking straw 1 may be consumed or may be re-used with another beverage.
Referring to
The arrangement of the main candy portion 2 and the secondary candy portion 3 of the candy drinking straw 1 provides an aesthetically appealing drinking straw design while providing the consumer with the choice of different flavors of the main and twisted candy portions 2 and 3. Structurally, the twisted candy portion 3 may reinforce the main candy portion 2 of the candy drinking straw 1 to make the candy drinking straw 1 more difficult to crack or break during transport, insertion, or use.
It should be understood that although the candy drinking straw 1 is described as having the twisted candy portion 3, more than one twisted candy portion or no twisted candy portion may be used in alternative embodiments of the invention. For example, the candy drinking straw 1 may be a single color/flavor solid candy shell. In another example, the candy drinking straw 1 may have several twisted candy portions 3, each providing a different color candy and/or a different candy flavor in addition to the main candy portion 2.
Although the twisted candy portion 3 shown in

In an exemplary embodiment of the invention, the outer diameter (OD) of the candy drinking straw 1 may be approximately 10 to 14 millimeters (mm), the inner diameter (ID) may be approximately 4 to 6 mm, and the thickness (x) of the candy drinking straw 1 may be approximately 3 to 4 mm. More particularly, the candy drinking straw 1 may be made such that the outer diameter (OD) is about 12 mm, the thickness (x) of the candy drinking straw 1 is about 3.5 mm, and the inner diameter (ID) of the candy drinking straw 1 is about 5 mm.
By comparison, most conventional plastic drinking straws have an inner diameter of about 7.5 mm. Other dimensions may also be used with embodiments of the present invention as long as the thickness (x) of the candy drinking straw 1 of the candy drinking straw 1 is large enough to withstand suction applied by the consumer in order to transport thick/heavy beverages without breakage. Additionally, the inner diameter (ID) of the candy drinking straw 1 may be large enough such that a thick milk shake, cookie crumbs, pieces of fruit, etc. may be transported therethrough by the suction applied by the consumer.
At step 2, the sugar is melted and combined with liquid glucose syrup to produce a sugar composition that may be made into solid candy when it is cooled. The sugar composition may then be combined with water in a ratio of about 1:1 in order to adjust the consistency of the mixture. At step 3, the sugar composition is heated. For example, the liquefied sugar may be heated in a vacuum cooking machine. During this step, the water is driven off, and the sugar composition becomes a soft relatively solid mass when the temperature of the vacuum cooking reaches around 150 degrees Celsius.
The sugar composition is then cooled at step 4. During this step, the sugar composition is removed from the vacuum cooking machine to be shaped, molded, processed, etc. into drinking straws. After the sugar composition is cooked, it has a consistency similar to that of dough or support clay. As the sugar composition cools, it can be shaped. For example, in step 4, the sugar composition may be placed on a cooling table and formed into a “brick.” Cooling devices known in the art may also be use in step 4.
At step 5, flavor and citric acid are added to the soft mass of sugar composition. Here, the mass of sugar composition is “pulled” to add air to the mass of sugar composition. The pulling may be performed by hand using a hook mounted on a wall or a table. Alternatively, the pulling can be performed by a machine. A dose of food grade colors of about 0.2% to 0.4% by weight of the sugar composition is then added. This step 5 may be performed while the sugar composition remains in the heat preserving condition.
Colors to be added to the sugar composition are then made at step 6. At step 7, color stripes are assembled about the sugar composition. A dose of the colors may be about 0.1% to 0.5% by weight of the cooked sugar composition. For example, red color and yellow color may be added to the sugar composition using government health department certified food colors. In this step, several soft masses of different color candy stripes may be positioned next to each other. Here, stripes of colored candy are mounted on the outside of the brick (i.e., the mass of sugar composition), which will eventually form the outside colors of the candy drinking straw 1.
A solid mold is then positioned inside the soft mass of sugar composition at step 8 for processing by the scroll machine.
The solid mold 42 may have a conical shape. In this case, the conical shape enables the sugar composition 40 to be gradually pushed around the surface of the solid mold 42 onto the support cord 44 with ease by the scroll machine (described below).
Referring to
The scrolls 9, 10, 11, and 12 rotate to roll and mold the sugar composition mass 40 (see
Although the solid mold 42 and the support cord 44 are shown and described as being distinct components coupled to each other at the coupling part 39 (see
Referring to
The sugar composition mass 40 is then twisted by a twisting machine.
A cutting machine cuts the twisted cylindrical sugar composition mass 40. The end of the support cord 44 may be disposed between the twisting device 50 and the cutting machine. Specifically, before being cut by the cutting machine, the twisted cylindrical sugar composition 40 is pushed off the end of the support cord 44 by pressure from other sugar composition mass 40 (i.e., “upstream” sugar composition mass 40) being pushed by the scroll machine 13 (see
In another embodiment of the invention, the support cord 44 may extend beyond the cuffing machine such that the sugar composition 40 is cut on the support cord 44. In this case, the sugar composition 40 may be removed from the support cord 44 after the cutting device 62 cuts the sugar composition 40. In this embodiment, the cutting device 62 cuts the sugar composition 40 around the support cord 44 without cutting the support cord 44. The support cord 44 with the cut candy segments (i.e., the sugar composition 40) can then be shaken such that the pieces of the cut sugar composition (candy) 40 fall from the support cord 44, one by one. Alternatively, the cut candy segments can be removed manually from the support cord 44. Other methods of removing the cut candy segments from the support cord 44 may alternatively be used with the present invention.
