Aluminum freezing box

Abstract

The invention relates to an aluminum freezing box consisting of a lower container and a box cover, which is characterized in that the lower container is manufactured by adopting a whole aluminum plate in an extension way; the box cover is extruded and formed by adopting an aluminum bar and then is cut into blocks by using a sawing machine; a layer of oxide film is attached on the surfaces of the lower container and the box cover; and bumps of 10mm are arranged around the circumference edge of the lower container, and six opening holes are arranged on a plane of the box cover. The invention has the advantages of ensure that the freezing box is not broken and the demoulding is easier because the bumps do not exist in the freezing box and improving the work efficiency. The surfaces of the lower container and the box cover are degreased and oxidized to make the aluminum freezing box clean, sanitary and easy to clean in use. The bumps arranged around the circumference edge can play the role of reinforcing. The six opening holes arranged on the box cover add the contact with outside, make excessive water of frozen blocks freely overflow and make the products of frozen blocks achieve the package requirements.

Description

technical field [0001] The invention relates to a container for freezing and processing aquatic products, in particular to an aluminum freezing box. Background technique [0002] China is currently the world's largest concentration of frozen aquatic products. In the aquatic product freezing market, a 2kg freezer box is required. At present, the freezer boxes on the market are made of plastic, stainless steel and welded aluminum. The freezer boxes made of stainless steel and plastic materials have poor thermal conductivity and low thermal efficiency; the freezer boxes made of welded aluminum are easily torn and damaged during use. [0003] In the case of low-temperature freezing, the freezing of aquatic products forms a huge pressure, which often causes the plastic freezer to burst; the welded aluminum freezer is torn from the weld; the stainless steel freezer is made of stainless steel with a thickness of 0.8-1.0mm. , very thin, and pits are prone to appear during use, whi...

Problems solved by technology

At present, the freezer boxes on the market are made of plastic, stainless steel, and welded aluminum. The freezer boxes made of stainless steel and plastic materials have poor thermal conductivity and low thermal efficiency; the freezer boxes made of welded aluminum are easy to tear and damage during use.

[0003] In the case of low-temperature freezing, the freezing of aquatic products creates huge pressure, which often causes the plastic freezing box to burst; the welded aluminum freezing box is torn from the weld; the stainless steel freezing box is made of stainless steel with a thickness of 0.8-1.0mm , very thin, prone to pits during use, which directly increases the difficulty of taking out ice cubes. It needs to be rinsed in hot water before taking out, and the operation is very difficult
