Problems solved by technology

However, D'Amelia et al. only care about the mixing process of one production volume, however, this process is not efficient, and there is no consistency of the product obtained by continuous mixing
Also, the single-step process is limited to chewing gums that contain unconventional gum bases that lack elastomers and other key components

example 1

[0092] Wide range of changes or modifications to the preferred embodiments of this invention will be apparent to those skilled in the art. The above-mentioned preferred embodiments and the examples to be described below are only used to illustrate the present invention, not to limit the present invention. For example, different continuous mixing devices and different mixer configurations may be used without departing from the invention as long as the chewing gum base and chewing gum product are produced in a single continuous mixer using a mixing L / D of no greater than 40. Example 1: Testing the suitability of a continuous mixer

[0093] The preliminary tests described below can be used to determine whether a particular continuous mixer with a particular configuration meets the requirements for an efficient mixer for use in practicing the process of the invention.

[0094] 35.7% butyl rubber (copolymer of 98.5% isobutylene-1.5% isoprene, molecular weight 120,000-150,000, POLY...

example 2-6

[0096] Also, the mixer must be of sufficient length to complete the manufacture of gum base and chewing gum products in a single mixer, with a total mixing L / D not exceeding 40. Any mixer meeting these requirements falls within the definition of a high efficiency mixer suitable for carrying out the method of the present invention. Example 2-6: Continuous production of chewing gum

[0097] The following example was carried out in the preferred manner above (unless indicated to the contrary) using a Buss kneader with a mixing screw diameter of 100 mm, having five mixing zones, a total mixing L / D of 19, and an initial conveying L / D of 1-1 / 3. No dies were used at the end of the mixer unless indicated to the contrary; the product mixture was discharged as a continuous rope. Each example was designed with a feed rate to obtain an output rate of 300 lbs / hr of chewing gum product.

[0098] The liquid components are fed by a volumetric pump into a large feed port and / or a smaller li...

example 2

[0104] This example illustrates the preparation of sugar chunk bubble gum. For this example, the shape of the mixer was slightly different from the preferred shape described above and was used in Examples 2-6. Specifically, a die with a circular hole of 30mm was installed at the outlet end of the mixer.

[0105] A blend of 68.9% high molecular weight polyvinyl acetate and 31.1% ground talc was added to the first large feed port 212 (see Figure 7 ). Polyisobutylene (preheated to 100°C) was also fed into port 212 at a rate of 3.95 lb / h. Downstream of the first mixing zone 220, acetylated monoglycerides are injected at a rate of 2.6 lb / h using a liquid injection (hollow barrel pin) port ( Figure 7 not shown) injection.

[0106] Additional polyisobutylene (100° C.) was added to the second large port 232 at a rate of 3.95 lb / h, glycerides of partially hydrogenated wood rosin at a rate of 13.4 lb / h. 43.6% glyceryl monostearate, A mixture of 55.9% triacetin and 0.5% BHT was ad...

Abstract

A system controller receives inputs of parameters necessary for prodn.. Ingredients are automatically and continuously fed and mixed to form a desired end product. During prodn. of chewing gum, the gum is automatically and continuously discharged from the mixer and can be automatically dusted, rolled, scored and wrapped. The system is continuously monitored with the appropriate sensing devices. Signals in dicative of the sensed conditions are sent to the controller, and the system automatically adjusts to produce a consistent end product. An alarm is activated upon sensing of a predetermined condition.

Description

field of invention [0001] The invention relates to a process control system and method for automatic and continuous production of chewing gum. Background technique [0002] Typically, gum base and gum products are produced in separate mixers, with different mixing techniques, and often in different factories. One of the reasons for this is that the optimum conditions for producing gum base and the optimum conditions for producing chewing gum from gum base and other components, such as sugar, flavors, are so different that bringing the two jobs together is Very impractical. On the one hand, chewing gum base production involves the dispersion (often high shear) of poorly miscible components such as elastomers, fillers, elastic pliers, gum base softeners / emulsifiers and sometimes waxes Mixing, often requires long mixing times. Chewing gum product manufacturing, on the other hand, involves blending gum base and other components, such as product softeners, bulk sweeteners, bul...
