Description

A rapid freezing device

technical field

The utility model relates to a rapid freezing device.

Background technique

Keeping food in an appropriate low temperature environment can prolong the storage period of food and maintain its freshness and nutritional content, while freezing and refrigerating food is the best way to prevent the reproduction of microorganisms and physical, chemical and biochemical changes , There are many types of food freezing systems, which are selected according to the requirements of food types, processing methods, quality, nutrition, and economic benefits. Among them, the rapid freezing method has the best effect and is most suitable for food freezing. Quickly extract the heat of the food and reduce the temperature of the food below the freezing point. During the manufacturing process of the frozen food, the taste of the food can be maintained and the structure of the food can be avoided to ensure the quality of the food. Generally, the method of quick freezing can be based on the cooling medium They are divided into three categories: immersion freezing, indirect contact freezing and forced air freezing. Among the above three rapid freezing methods, forced air freezing is more popular in the industry and widely accepted. use. The refrigeration device with strong air supply is composed of a tunnel refrigeration body, a conveyor belt, several motors, several fans, a cold exhaust pipe and two compressors. Among them, several partitions are arranged between the tunnel refrigeration body to make the tunnel refrigeration body Several independent spaces are formed inside, and through-holes are provided between the outside of the tunnel refrigeration body and each independent space, and doors are provided at the openings of each independent space, and the conveyor belt is installed between the through-holes of the tunnel refrigeration body. It is used to drive the fans. The motor and fan are installed above the tunnel freezer body. The motor is located outside the tunnel freezer body. The fan is installed inside the tunnel freezer body. Each independent space is equipped with a motor and a fan. The cooling pipe Installed on the inner side of each independent space of the tunnel refrigeration body, the two compressors are connected in series to the cold discharge pipe, first use the first compressor to cool, then connect to the second compressor for refrigeration, and finally connect to the cold discharge pipe To reduce the temperature of the tunnel freezing body.

However, the above-mentioned refrigerating device has the following disadvantages in actual use: First, the above-mentioned refrigerating device installs the motor and the fan above the tunnel freezing body, wherein the motor is located outside the tunnel freezing body, and the fan is located on the tunnel freezing body. Inside the body, only the top surface of the food is the windward side, so that the bottom surface of the food is less likely to be blown by the cold wind, resulting in a slower cooling rate; second, the above-mentioned refrigerating device is located above the tunnel refrigerating body due to the fan, resulting in The cooling rate of the bottom surface of the food is relatively slow, resulting in uneven quality of the food after freezing.

Contents of the invention

The purpose of this utility model is to provide a rapid freezing device, so that both the top surface and the bottom surface of the food can be blown by cold wind, so as to achieve an average cooling rate and ensure the quality of the product.

In order to achieve the above object, the rapid freezing device of the utility model has a freezer, and a diverter plate is arranged inside the freezer, several door panels are respectively arranged on both sides of the diverter plate, and a conveyor belt is arranged above the diverter plate. The two ends of the warehouse are provided with item delivery ports corresponding to the conveyor belt, while the freezer is equipped with a compressor, and the compressor is equipped with several cold exhaust pipes at the top of the freezer, so that the low-temperature air blows through the top surface of the food on the conveyor belt. Finally, it will be blocked by the splitter plate and blow back to the bottom surface of the food, so that both the top surface and the bottom surface of the food can be blown by the cold wind to cool down on average.

Another purpose of the present invention is to make the air inside the freezer recirculate to maintain the low temperature environment inside the freezer, so that the food that continues to enter the freezer can be continuously cooled.

In order to achieve the above purpose, the utility model provides a rapid freezing device. There is a gap between the two sides of the distribution plate and the door panel of the freezer, and several fans are installed above the door panel, so the low-temperature air blocked by the distribution plate will partly Blow back to the bottom surface of the food, and the rest of the low-temperature air will be blown to both sides of the splitter plate along the inclination of the splitter plate, and then blown to the aisle outside the door panel through the gap between the splitter plate and the door panel, and the fan above the door panel will The air in the aisle is pumped to the inside of the freezer to cool down, so that the low-temperature air circulates repeatedly in the freezer.

As an improvement, a partition is provided above the conveyor belt, and the partition is provided with air holes for the low-temperature air to penetrate the partition and blow to the top surface of the food.

As an improvement, the splitter plate is inclined downward from the center line to both sides, so that the low-temperature air will blow to both sides of the splitter plate along the inclination of the splitter plate.

Compared with the prior art, the rapid freezing device of the utility model can make the top surface and the bottom surface of the food can be blown by the cold wind to achieve an average cooling rate to ensure the quality of the product; at the same time, the air inside the freezer can be repeatedly circulated , to maintain the low temperature environment inside the freezer, so that the food that continues to enter the freezer can be continuously cooled.
