Abstract

The invention provides an on-line liquid nitrogen freezing apparatus capable of realizing continuous production. The on-line liquid nitrogen freezing apparatus is integrally configured with a production line and comprises a cabinet body, a movable cabinet door and a cabinet door frame, wherein the cabinet body and the cabinet door comprise shells and inner walls, and heat insulation layers are arranged between the shells and the inner walls; the cabinet door is arranged on the front and rear sides of the cabinet body; the door frame and the cabinet body are of an integrated design; two sides of the door frame are provided with movable sliding rails; the top end of the movable cabinet door is provided with a transmission shaft; the transmission shaft is driven by a motor; one end of a transmission chain is connected with the transmission shaft, and the other end of the transmission chain is connected with fixed structures located on both sides of the cabinet doors; when the cabinet doors are to be opened, the motor drives the transmission shaft to rotate so as to lift the cabinet doors upward, thereby realizing opening of the cabinet doors; and transmission rollers are arranged in the cabinet body. The on-line liquid nitrogen freezing apparatus is provided with the front and rear openable cabinet doors, can automatically sense a material rack to be frozen or cryogenically processed, automatically accomplishes a series of operations like the lifting and closing of the cabinet doors, liquid nitrogen conveying, freezing or copious cooling and discharging, and is high in work efficiency, small in occupied land area and reduced in effective working space.

Description

technical field [0001] The invention relates to the technical field of freezing equipment, in particular to an on-line liquid nitrogen freezing equipment capable of continuous production. Background technique [0002] Food freezing technology and freezing equipment are widely used in the production, transportation and storage of perishable foods such as meat, poultry, aquatic products, milk, eggs, vegetables and fruits. Frozen food has better nutritional preservation, easy access, and is not easy to deteriorate. Hygienic and economical. Liquid nitrogen is the most environmentally friendly and efficient way of cooling and freezing today. The ultra-cold temperature of liquid nitrogen can quickly and effectively cool down food, ensuring that the moisture and quality of food are completely preserved, and the original color, taste and originality of frozen food are guaranteed. quality. In the production process of frozen food, tunnel type freezing equipment and cabinet type fre...
