Description

Technical Field

[0001] This invention relates to the field of food quick-freezing technology, specifically to a novel reciprocating tray-type food quick-freezing machine. Background Technology

[0002] With the advancement of industrialization and the acceleration of the pace of life, pre-cooked meals have rapidly emerged due to their advantages of standardization and convenience, becoming an important development direction in the food industry. They not only meet the needs of chain restaurants for large-scale expansion, but also provide consumers with efficient dietary solutions, while driving the deep processing of agricultural products and the upgrading of food technology.

[0003] As a core piece of equipment in the production of prepared foods, quick-freezing machines need to rapidly lower the core temperature of food to below -18°C, preserving the original quality of the food by forming tiny ice crystals. Currently, the mainstream types include spiral quick-freezing machines, tunnel quick-freezing machines, and fluidized bed quick-freezing machines. However, given the diverse packaging sizes of prepared foods, traditional quick-freezing machines have revealed many problems: products are prone to stacking and jamming during freezing, leading to uneven heat exchange; the equipment has a complex structure, large footprint, and high cost for construction and maintenance; during operation, malfunctions such as conveyor belt jamming, tooth skipping, and product slippage frequently occur; there is a lack of automated unpacking function adapted to boxed products, resulting in high labor costs, inability to produce continuously, and difficulty in meeting the industry's large-scale needs.

[0004] Based on this, this solution proposes a novel reciprocating tray-type quick-freezing machine for food. Summary of the Invention

[0005] The purpose of this invention is to provide a novel reciprocating tray-type quick-freezing machine for food to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel reciprocating tray-type quick-freezing machine for food, comprising a quick-freezing machine, a feeding conveyor belt, a handle, and a door. The quick-freezing machine is provided with a clamping component for clamping tray-type food, a rotation drive component for driving the clamping component to rotate the food, a spray cooling component for spraying cold air, a reciprocating drive component for driving the spray cooling component to move back and forth, and a feeding drive component for driving the quick-frozen food to fall onto the feeding conveyor belt.

[0007] Preferably, the rotation drive assembly includes four sprockets, two conveyor chains, and two second motors. The two second motors are fixedly installed on one side of the quick-freezing machine, and the output shafts of the two second motors are respectively fixedly connected to the corresponding sprockets. The four sprockets are rotatably installed inside the quick-freezing machine, and the same conveyor chain is sleeved between two sprockets on the same side.

[0008] The above technical solution, with dual second motors driving synchronously, provides stable power to the sprockets and conveyor chain, avoiding malfunctions caused by excessive load on a single motor. The four sprockets form a symmetrical support structure, allowing the conveyor chain to circulate smoothly and drive the clamping components and food to rotate evenly up and down, ensuring that all parts of the food can fully contact the cold air, laying the foundation for uniform quick freezing. Furthermore, the mechanical transmission structure experiences less wear and has a long service life.

[0009] Preferably, the clamping assembly includes multiple fixed plates, fixed rods, sliding rods, sliding sleeves, clamping electric telescopic rods, and U-shaped clamping plates. The multiple fixed plates are all hinged at equal distances on two conveyor chains. Fixed rods are fixedly installed on both sides of the top of any fixed plate. Sliding rods are fixedly installed inside any fixed rod. Two sliding sleeves are slidably sleeved on any sliding rod. Two clamping electric telescopic rods are fixedly installed inside the corresponding fixed rods. The output shaft of the clamping electric telescopic rod is fixedly connected to the corresponding sliding sleeve. The same U-shaped clamping plate is fixedly installed between the two corresponding sliding sleeves.

[0010] Using the above technical solution, multiple equally spaced fixing plates can simultaneously support multiple trays of food, improving production efficiency. The cooperation between the sliding rod and the sliding sleeve provides precise guidance for the U-shaped clamping plate, and the electric telescopic clamping rod can precisely control the clamping range to adapt to trays of different sizes. The U-shaped clamping plate fits snugly against the edge of the food, clamping it firmly and effectively preventing the food from slipping or tipping over during rotation and quick-freezing, ensuring the integrity of the food's appearance and the quick-freezing effect.

[0011] Preferably, the feeding drive assembly includes multiple feeding electric telescopic rods, which are all hinged at equal distances on two conveyor chains. The output shaft of any feeding electric telescopic rod is hinged to the corresponding fixed plate to drive the fixed plate to flip upward.

[0012] Using the above technical solution, the electric telescopic rod for feeding is hinged to the fixed plate, which can smoothly transmit driving force and achieve precise flipping of the fixed plate. After the food is quick-frozen, the telescopic rod extends and pushes the fixed plate upward to flip it. The food then falls smoothly onto the feeding conveyor belt under the action of gravity. The whole process is automated and requires no manual intervention, which reduces labor costs and avoids food contamination or damage caused by manual operation, ensuring smooth continuous production.

[0013] Preferably, the spray cooling assembly includes two long rods, two movable plates, and multiple nozzles. The two long rods are fixedly installed inside the quick-freezing machine, the two movable plates are slidably sleeved on the two long rods, and the multiple nozzles are fixedly installed at intervals at the bottom of the two movable plates and are flexibly connected to the cold air structure inside the quick-freezing machine.

[0014] Using the above technical solution, the long bar provides stable support and sliding guidance for the movable plate, ensuring that the movable plate remains horizontal when moving. Multiple spaced nozzles expand the coverage area of ​​the cold air, and the flexible connection design ensures stable and sealed cold air delivery without restricting the movement of the movable plate, allowing the cold air to be sprayed continuously and evenly, creating a stable cooling environment.

[0015] Preferably, the reciprocating drive assembly includes a first motor, a reciprocating lead screw, a lead screw guide sleeve, and two connecting rods. The first motor is fixedly installed on the top of the quick-freezing machine, and its output end is fixedly connected to the reciprocating lead screw. The lead screw guide sleeve is threaded onto the reciprocating lead screw. One end of each of the two connecting rods is hinged to the lead screw guide sleeve, and the other end is hinged to the two movable plates, which are used to drive the two movable plates to move synchronously left and right.

[0016] Using the above technical solution, the first motor drives the reciprocating lead screw to rotate, causing the lead screw guide sleeve to move up and down reciprocally. Power is transmitted through the connecting rod, causing the movable plate to slide back and forth along the long rod. The nozzle moves with the movable plate, coordinating with the up and down rotation of the food to achieve all-round, dead-angle-free cooling, completely solving the problem of uneven heat exchange in traditional quick-freezing machines.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By working together with the reciprocating drive component and the uniform spraying component, the food is frozen in all directions and evenly, effectively improving the product quality and taste. Second, the clamping components are compatible with different sized trays of food, the feeding process is highly automated, the equipment has a compact structure and small footprint, stable operation and few failures, which reduces equipment cost, maintenance cost and labor cost, and meets the needs of large-scale production in the industry.
