Technical Field
[0001] The utility model relates to the technical field of puffing machines, in particular to a single-screw low-temperature wet-process puffing machine. Background Art
[0002] Wet extruder is a kind of food processing equipment, mainly used for making puffed food. This machine evaporates the water in the raw materials by heating and pressurizing, so that the raw materials expand under high temperature and pressure, thus forming a porous and crispy structure. Single screw low temperature wet extruder is a special type of wet extruder, which adopts a single screw structure and performs extrusion at a relatively low temperature. This equipment is suitable for some temperature-sensitive raw materials, such as those containing high protein or high fat. This extruder uses a single screw to mix, compress and extrude the raw materials. Unlike the traditional high temperature extrusion method, the low temperature wet extruder performs the extrusion process at a lower temperature, which can reduce the damage to the nutrients of the raw materials and maintain the nutritional value and natural flavor of the product. Due to the low operating temperature, the equipment has higher requirements for temperature and humidity control, so it is usually equipped with a precise control system to ensure the consistency of product quality.
[0003] In the prior art, when a material is puffed by a single-screw low-temperature wet extruder, water is generally directly added to the material, and then the wet material is put into a hopper, so as to achieve extrusion and puffing of the material by the single-screw low-temperature wet extruder. Since the material and water cannot be mixed well, the wet material may have uneven humidity after entering the hopper, which will cause uneven material quality, thereby affecting the puffing effect and quality. Therefore, in order to solve the above problems, a single-screw low-temperature wet extruder is proposed. Utility Model Content

Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.
[0023] A single-screw low-temperature wet-process extruder comprises a machine body, which comprises a machine case 1. A hopper 11 is arranged at the top of the machine case 1. A feed port 12 is fixedly connected to the surface of the hopper 11. A discharge pipe 13 is arranged at the bottom of the hopper 11. The discharge pipe 13 is fixedly connected to the machine case 1. A screw conveying rod 14 is movably connected to the inner side of the machine case 1. A first motor 15 is fixedly installed on the surface of the machine case 1. The screw conveying rod 14 is fixedly connected to the output end of the first motor 15. A mold 16 is arranged on the inner side of the machine case 1. By adding water to the material and putting it into the feed port 12, the wet material can enter the machine case 1 through the hopper 11. The material is subjected to low-temperature treatment in the machine case 1 and is pushed to the mold 16 under the action of the screw conveying rod 14. Then, the material is compressed and instantly extruded. Due to the pressure difference between the mold 16 and the external environment, the material is suddenly released to a normal temperature and pressure state. Then, the water inside the material is rapidly vaporized, resulting in rapid volume expansion, thereby achieving an extrusion effect.
[0024] A stirring mechanism is provided on the inner side of the hopper 11, and the stirring mechanism includes a rotating rod 2, which is movably connected to the inner side of the hopper 11, and a connecting box 21 is provided on the top of the hopper 11, and a second motor 22 is fixedly installed on the inner side of the connecting box 21.

Through the arrangement of the second fixed rod 27 and the second stirring rod 28, the inner side of the discharge pipe 13 can be rotated, thereby facilitating better discharge of the material through the discharge pipe 13.
[0026] Furthermore, the rotating rod 2 is fixedly connected to the output end of the second motor 22, the rotating rod 2 is movable on the inner side of the connecting box 21, and the first stirring rod 23 is fixedly connected to the rotating rod 2 in twelve groups.

Through the setting of the scraper 26, the scraper 26 can rotate along with the rotation of the rotating rod 2, thereby scraping the wall of the hopper 11 and avoiding the adhesion of materials.

[0029] Furthermore, one end of the movable rod 34 is movably connected to the moving block 33 through a rotating shaft, and the other end of the movable rod 34 is movably connected to the connecting box 21 through a rotating shaft. Both ends of the spring 35 are respectively fixed to the hopper 11 and the connecting box 21, and the moving block 33 is movably connected to the connecting block 36 and the slide groove 37. Through the setting of the spring 35, the connecting box 21 and the second motor 22 can be protected, and the movement of the movable rod 34 can be prevented from causing a collision between the connecting box 21 and the hopper 11.
[0030] Working principle: When in use, the second motor 22 is electrically connected to an external power source, and the staff starts the second motor 22 by pressing a switch.

[0031] The third motor 32 is electrically connected to an external power source. The staff starts the third motor 32 by pressing a switch. The operation of the third motor 32 drives the reciprocating screw 31 to rotate. The moving block 33 is limited by the connecting block 36 and the slide groove 37, and will move horizontally under the action of the reciprocating screw 31. Then the connecting block 36 slides on the surface of the slide groove 37, so that the movable rod 34 can move and drive the connecting box 21 to rise and fall. Then, during the rotation of the rotating rod 2, the connecting rod 24, the scraper 26 and the second stirring rod 28 can rotate and rise and fall at the same time. The spring 35 is deformed during the process of the connecting box 21 rising and falling, which can help the connecting box 21 to reset.
