Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of compound freeze-drying production equipment, and specifically relates to a low-cost efficient sterilization compound freeze-dried product production system. BACKGROUND

[0002] Meat compound freeze-drying is a process of mixing meat with other ingredients (such as auxiliary materials, stabilizers, seasonings, etc.) and then preparing solid powder or block-shaped objects through freeze-drying technology. This technology is widely used in the food industry, which can effectively maintain the nutritional ingredients, flavor and texture of meat, and prolong the shelf life of the product.

[0003] At present, the existing compound freeze-drying production process is: raw material buffering-raw material crushing-raw material mixing-material forming-material freezing-material freeze-drying-product selection-product packaging-irradiation sterilization-shipping. In the existing compound freeze-drying production system, the product cannot be sterilized before packaging, and can only be sterilized by irradiation after packaging. However, the existing production system uses irradiation sterilization after packaging, which shortens the shelf life of the product and causes abnormal changes in the flavor of the freeze-dried product in a short period of time. UTILITY MODEL CONTENT

[0004] In view of the problems and deficiencies in the prior art, the utility model provides a low-cost efficient sterilization compound freeze-dried product production system.

[0005] The utility model technical scheme is as follows:

[0008] The complex freeze-dried product production system further comprises a storage rack and an AGV trolley, the storage rack is arranged in the processing chamber and located downstream of the sectioning machine, and is used for temporarily storing the sectioned materials; and the AGV trolley transfers the materials between the storage rack and the freeze-drying bin along a planned path. The storage rack is provided with a sterilization box, and the sectioned materials are placed on the storage rack through the sterilization box. The materials are ensured to be in a sterile environment during the transfer process of the AGV trolley.

[0009] During work, materials such as chicken breasts are stirred and crushed by a meat grinder, and then the aggregate enters a bone grinder to crush the bone, and the meat is further stirred and crushed by a chopping mixer and then enters a stirring machine to be mixed, and at the same time of mixing, an ozone generator is started to sterilize the materials, the sterilized materials enter an extruder also arranged in a sterile processing chamber for forming processing, and then enter a single freezer for shaping, the shaped materials are conveyed to a cutting machine by a conveyor for sectioning, the sectioned materials are temporarily stored on the storage rack by the sterilization box, and then are transferred to the freeze-drying bin by the AGV trolley along the planned path for freeze-drying, and the freeze-dried materials are directly packed into boxes after being packed by a packing machine, without the need for irradiation sterilization treatment. Thus, the ozone sterilization process in the production process is realized, the product flavor and shelf life are ensured to the greatest extent, and the production cost can be reduced.

[0010] The complex freeze-dried product production system with low cost and high efficiency sterilization comprises a box body, a bin cover connected to the top of the box body through a flip cover mechanism, a bracket arranged on the rear side of the box body, a gas inlet pipe arranged on the side wall of the box body, and a plurality of gas inlet pipes communicated with the gas inlet pipe.

[0011] According to a specific embodiment, a flow regulating valve is arranged on the connecting hose of the stirring machine close to one end of the gas branch pipe, and a timer is arranged on the box body, and the flow regulating valve and the timer are both in communication connection with the control unit. The flow regulating valve is used for controlling the flow of ozone, and the timer is used for controlling the ozone inlet time, and the flow and the inlet time are controlled through the control unit to realize the control of the amount of ozone entering the box body, and then the ozone concentration in the stirring machine reaches the set requirement.

[0012] According to a specific embodiment, the gas inlet pipes are upwardly inclined and symmetrically arranged on the front side wall and the rear side wall of the box body. The upwardly inclined arrangement of the gas inlet pipes is beneficial to welding processing and facilitates the connection operation with the connecting hose.

[0013] In order to improve the uniformity of ozone filling and control the manufacturing cost, three gas inlet pipes are arranged on the front side wall and the rear side wall of the box body respectively, the three gas inlet pipes on one side of the box body are communicated with the corresponding side gas branch pipe through the connecting hose, and one flow regulating valve is arranged on each connecting hose.

[0014] Furthermore, the gas inlet pipe is detachably connected with the connecting hose through a pipe clamp. This facilitates the installation and maintenance of the equipment. The gas branch pipe arranged on the rear side of the box body is located below the bracket.

[0015] Based on actual test results, preferably, the diameter of the air intake pipe is 15-25mm, and the diameter of the air supply branch pipe is 50-80mm.

[0016] In addition, the mixer's casing contains an agitator and a weighing sensor. The agitator is rotatably connected to the side wall of the casing and is driven by a motor to rotate; the agitator is used to mix materials. The weighing sensor is located at the bottom of the casing and communicates with the control unit to measure the weight of the materials fed into the casing in order to control the ozone concentration.

[0017] The beneficial effects of this utility model are:

[0018] Ozone has extremely strong oxidizing properties, which can destroy the cell walls and cell membranes of microorganisms, causing the cell contents to leak out and thus killing the microorganisms. It is a highly effective disinfectant that can effectively kill bacteria, viruses, fungi, spores and other microorganisms.

[0019] The adjusted compound freeze-dried product production system incorporates the main sterilization process during raw material mixing. As the raw materials enter the mixer, an ozone generator is simultaneously activated to inject ozone into the mixer for sterilization. Compared to production systems that perform irradiation sterilization during packaging, this system offers higher sterilization rates, lower costs, and, since ozone decomposes to produce oxygen (O2), it leaves no harmful residues and offers greater safety. Therefore, it maximizes product flavor and shelf life while reducing production costs. Attached Figure Description
