TH35958A - Injection of chocolate - Google Patents

Abstract

DC60 (07/10/40) This process is for injecting fatty, plasticized liquids into a mold. It involves feeding the fatty, plasticized material into an injection molder and applying pressure to the liquid or semi-liquid, leak-proof fatty, plasticized material upstream of the flow constriction. Temperature, pressure, shrinkage ratio, and injection rate are then applied to the material, removing most of the fatty, plasticized material, leaving a visibly liquid or semi-liquid, leak-proof product. This results in a homogeneous, axially shaped product with a cross-section similar to the injection molding nozzle, which is temporarily plasticized and can be physically manipulated, cut, or reshaped before losing its elasticity. A vacuum is then applied to the fatty, plasticized material upstream of the flow constriction. The process of injecting fatty, fat-containing material into a plasticizer involves feeding the fatty material into an injection molder and applying pressure to the liquid or semi-liquid, leak-proof fatty material upstream of the flow narrowing. Temperature, pressure, shrinkage ratio, and injection rate then remove the fatty material, leaving a visibly liquid or semi-liquid, leak-proof product. This results in a homogeneous, axially shaped product with a cross-section similar to the injection molding nozzle, allowing it to be physically manipulated, cut, or reshaped before losing its elasticity. A vacuum is then applied to the fatty material upstream of the flow narrowing.

Claims (9)

1. The process of injection molding of fatty, encapsulated material into an injection molder involves feeding the fatty, encapsulated material into an injection molder. Pressure is then applied to the liquid or semi-liquid, leak-proof fatty, encapsulated material upstream of the injection flow. Temperature, pressure, shrinkage ratio, and injection rate are then applied to the material, removing the encapsulated material and leaving it in a visibly liquid or semi-liquid, leak-proof form. This results in a homogeneous, axially shaped product with a cross-sectional area similar to the injection molding mold's outlet. This product is temporarily plasticized and can be physically manipulated, cut, or reshaped before losing its elasticity or plasticity. A vacuum is then applied to the fatty, encapsulated material upstream of the injection flow. 2. The process referred to in Claim 1, whereby, prior to being fed into the injector, the fatty dessert material may be retained in a hopper or other container, and a vacuum is applied to the fatty dessert material wherever it is located between the hopper and the injector feed, or while the fatty dessert material is being fed into the injector. 3. The process as referred to in claim 2, whereby the valve is placed between the hopper or other vessel and the injection feeder. 4. The process as referred to in claim 3, whereby the valve shall be a rotary valve. 5. The process as referred to in Claim 1, where the vacuum pressure ranges from 10 to 500 millibars. 6. The process referred to in Claim 1, whereby the injection machine shall be a push injection machine, single-screw injection machine, twin-screw injection machine or a conforming machine. 7. The process referred to in Claim 1, in which chocolate or sweet materials containing fat may be injected together with other chocolate or sweet materials containing fat, or other food materials. 8. The process referred to in claim number 7, whereby the other food materials are ice cream, sherbet, yogurt, mousse, fondant, praline, marshmallow, nougat, jelly or other food materials. 9. The injected, fat-containing dessert material can be obtained by any of the processes described in one of the previously stated claims. (Claims 9, 2 pages, 1 image)
