Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to a thawing device for frozen poultry. Background Technology
[0002] In the food processing industry, the thawing of frozen poultry is a crucial step. Traditional methods of thawing frozen poultry have many drawbacks. For example, natural thawing is time-consuming and inefficient, failing to meet the needs of large-scale production; while water bath thawing, although relatively faster, easily leads to water contamination of the thawed product, increasing the risk of microbial growth and affecting product quality. Furthermore, traditional thawing methods often require significant manual operation, increasing labor costs and human error. With the development of the food processing industry, the demand for efficient, hygienic, and highly automated poultry thawing equipment is becoming increasingly urgent. Utility Model Content
[0003] The purpose of this invention is to provide a thawing device for frozen poultry products, so as to solve the technical problems of high manual intervention and poor thawing effect in the prior art.
[0004] To solve the above problems, the poultry frozen product thawing device involved in this utility model adopts the following technical solution:
[0005] This utility model provides a poultry frozen product thawing device, including a bubble thawing tank and a suspended conveyor system for transporting frozen products. The bubble thawing tank and the cleaning device are both located below the conveying path of the suspended conveyor system. The cleaning device is located on the discharge side of the bubble thawing tank. The cleaning device includes a water tank, side plates set on both sides of the water tank, and a top plate set above the side plates. A channel for the suspended conveyor system to pass through is left between the two top plates. Coils are installed on the inner side of the side plates and the inner side of the top plate. Spray nozzles are set on the peripheral wall of the coils at intervals along their length and are connected. An external water supply device is connected to the coils.
[0006] Preferably, it also includes two temperature sensors, a heater, a controller, a heating water circuit, a cold water bypass, and a main pipeline. The outlet of the external water supply device is connected to the heater through the heating water circuit. The heater is connected to the coil through the main pipeline. One temperature sensor is located in the bubble defrosting tank, and the other temperature sensor is located in the main pipeline. The outlet of the external water supply device is also connected to the main pipeline through the cold water bypass, and the temperature sensor is located between the cold water bypass and the heating water circuit. Electronic regulating valves are installed on both the cold water bypass and the coil. The controller is electrically connected to the electronic regulating valves and the two temperature sensors.
[0007] The beneficial effects of this utility model are as follows:
[0008] This utility model provides a poultry frozen product thawing device. The bubble thawing tank generates bubbles to agitate the water flow, accelerating the heat transfer around the frozen product. The difference from the prior art is that the suspended conveyor system realizes automatic conveying of frozen products, eliminating the need for manual handling or transfer, reducing process interval time. The inner side of the side plate and top plate of the cleaning device are equipped with coils, and the nozzles on the coils form a three-dimensional water spray network on the top and sides, which can rinse the frozen products in all directions without cleaning dead corners, effectively removing impurities and debris generated during thawing from the surface of the frozen products, ensuring the cleanliness of the products. The frozen products are suspended throughout the process and do not come into contact with the ground or transfer containers, reducing the probability of microbial contamination.

[0013] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] This utility model provides a poultry frozen product thawing device, as shown in the figure. It includes a suspended conveyor system 3 for conveying frozen products and a bubble thawing tank 1 for cleaning frozen products. The bubble thawing tank 1 and the cleaning device 2 are both located below the conveying path of the suspended conveyor system 3. The suspended conveyor system 3 and the bubble thawing tank 1 are existing devices. The protection point of this application is that a cleaning device for cleaning frozen products after the thawing step is added. For ease of understanding, the general structure of the suspended conveyor system 3 is as follows: a frame located above the bubble thawing tank 1, a conveyor rotatably mounted on the frame, chains spaced along the length of the conveyor, and foot hangers for suspending poultry at the bottom of the chains. The conveyor rotates to move the frozen poultry through the chains. The bubble thawing tank 1 uses the water flow generated by bubbles to agitate and accelerate the heat transfer around the frozen products, shortening the thawing time. The cleaning device 2 is located on the discharge side of the bubble thawing tank 1, so that the frozen products can enter the cleaning stage after thawing, realizing a continuous assembly line operation. The cleaning device 2 specifically includes a water tank, side plates on both sides of the water tank, and a top plate above the side plates. A channel is left between the two top plates for the suspended conveyor system 3 to pass through, ensuring that the suspended conveyor system 3 can pass smoothly through the cleaning device 2. At the same time, the frozen products can be within the effective cleaning range of the cleaning device 2 during the conveying process. Coils are installed on the inner side of the side plates and the inner side of the top plate. Spray nozzles are installed at intervals and connected along the length of the coils. An external water supply device is connected to the coils. The cleaning water provided by the water supply device is sprayed evenly from the spray nozzles through the coils to rinse the frozen products in all directions. Furthermore, this device may also include a temperature sensor, a heater, a controller, a heating water circuit, a cold water bypass, and a main pipeline. The outlet of the external water supply device is connected to the heater through the heating water circuit. The heater is used to heat the water flow. The heater is connected to the coil through the main pipeline. One temperature sensor is located in the bubble defrosting tank 1 to monitor the water temperature in the defrosting tank. Another temperature sensor is located in the main pipeline to monitor the temperature of the cleaning water entering the coil. The outlet of the external water supply device is also connected to the main pipeline through the cold water bypass. The temperature sensor is located between the cold water bypass and the heating water circuit. Electronic regulating valves are installed on both the cold water bypass and the coil. The controller is electrically connected to the electronic regulating valve, the two temperature sensors, and / or the heater. The temperature sensor monitors the water temperature in real time and transmits the signal to the controller. The controller controls the opening of the electronic regulating valve and the heating temperature of the heater based on the difference between the two temperature sensors, and adjusts the mixing ratio of cold water and hot water, thereby accurately controlling the temperature of the cleaning water to be consistent with the water temperature in the bubble defrosting tank 1. The control function of this device is to ensure that the temperature of the cleaning water entering the coil is consistent with the temperature inside the bubble defrosting tank 1, so as to prevent the food's texture from being damaged due to an excessive temperature difference between the cleaning and defrosting temperatures. The method is as follows: part of the external water supply is heated by a heater and then flows to the coil through the main pipe; part of the external water supply directly enters the main pipe and mixes with the heated water; the controller adjusts the opening of the electronic flow valve based on the real-time temperature difference between two sensors.If the water temperature in the main pipeline is lower than that in the bubble thawing tank 1: reduce the valve opening (reduce the cold water flow rate) or increase the heater power (increase the heating water temperature); if the water temperature in the main pipeline is higher than that in the bubble thawing tank 1: increase the valve opening (increase the cold water flow rate) and reduce the mixed water temperature.
[0015] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
