Description

Technical Field

[0001] The present invention relates to food machinery, and particularly to a device for receiving fluid food materials. Background Art

[0002] With the continuous development of the catering industry, people's attention to diet and high requirements for food quality, the demand for fluid food materials such as soups, milk, beverages, and seasoning sauces is becoming more and more extensive. The national food safety law stipulates that some fluid food materials can provide a good sense of experience to the human body only under the condition of heat preservation and temperature control.

[0003] Currently, many hot fluid food materials are placed in a heat preservation cylinder, and then an outlet is opened at the lower part of the cylinder. When needed, the outlet is opened to receive the fluid food materials, and the outlet is closed after receiving is completed. The disadvantages of the existing device for storing and receiving fluid food materials are as follows: the flow rate of the fluid coming out of the bottom outlet is relatively large. If you hold it by hand, it may scald your hand; if you don't hold it by hand, it may shake. However, if the outlet is not placed at the bottom, it is easy to occur that the fluid at the bottom inside cannot be completely used up, and finally it will precipitate, affecting the taste of the overall food material and even causing food safety accidents.
