Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a twin-screw extruder for food processing. Background Art

[0002] The twin-screw extruder for food processing is a device used to produce extruded food. It processes raw materials into light, porous, and crispy extruded food through mechanical action and heat treatment. The extruder can be used to make various extruded foods, such as extruded grains, extruded corn, extruded rice, and extruded beans. By extruding grains or other raw materials, it can make them easier for the human body to digest and absorb, and it is also convenient to add nutrients such as vitamins and minerals. Twin-screw extruders are widely used in the food industry. They not only improve the production efficiency of food, but also provide possibilities for food innovation and diversification. By precisely controlling the extrusion process, food products with specific characteristics and uses can be obtained;

[0003] The Chinese patent authorization announcement number is CN213404831U, and the name is a twin-screw extruder, which includes an extruder body and a feeding device. The outer surface of one side of the extruder body is fixedly connected to the feeding device near the upper end. The output end of the motor drives the threaded rod to make the sleeve rise, and the receiving plate above the sleeve contacts the feeding device at a suitable position. There is no need to manually hold the receiving belt. When the fixed plate is squeezed by the conical feeding port, the spring inside the slide groove contracts, and the elastic force of the spring and the feeding port of the feeding device are squeezed and squeezed each other, so that the bag opening of the receiving bag is fixed by the squeezing force, and the magnitude of the force on the spring changes the extension length of the slide rod, so that receiving bags of different sizes can be fixed;

[0004] The disadvantages of the above scheme are that although the above scheme can be used to connect the materials, it cannot heat and keep them evenly when the extruder is working. Uneven heating will lead to inconsistent quality of the extruded products, some places will be over-expanded and some places will be under-expanded. The heating system needs to consume more energy to compensate for the low temperature in some areas. In addition, the above device cannot cut the food and may not be suitable for subsequent processing and packaging processes. Failure to cut or poor cutting effect will bring difficult technical problems to these processes. Utility Model Content
