Description

Technical Field

[0001] The utility model belongs to the field of factory silkworm feed production, and in particular relates to a mixer in the feed production process. The mixer has a cooling function. Background Art

[0002] The traditional way of raising silkworms is to raise them in a small family workshop. It is a fully artificial silkworm raising method. From silkworm eggs to cocoons, it is all done manually. It is time-consuming and labor-intensive, and the breeding efficiency is very low. In addition, due to seasonal conditions, silkworms can only be raised at specific times. The annual output of silkworm cocoons is extremely low, which cannot meet the needs of today's society and has been gradually eliminated by society. In order to make up for the shortcomings of traditional workshop-style silkworm raising, large-scale and factory-based silkworm raising technology has been applied. In large-scale breeding technology, if mulberry leaves are used as feed, it is completely impossible to meet the requirements of factory-based silkworm raising. Therefore, artificial feed plays an important role in factory-based and large-scale silkworm raising technology.

[0003] The artificial feed production process includes three steps: raw material processing, cooking and feed cooling. The raw material processing step is to mix the raw materials after crushing and other treatments to obtain dry powder. The cooking step is to mix the dry powder with water and stir to obtain raw material, and then the raw material is steamed and cooked to obtain feed. Finally, the feed is cooled after cooking through the feed cooling step.

[0004] The utility model patent with the publication number CN114287523A discloses a large-scale artificial feed production process applied to factory silkworm breeding, and specifically discloses: Step 2, mixing powder and water: water and powder are automatically added to the mixer, and stirring begins. During the stirring process, observe whether the state and color of the feed are normal; after stirring, discharge the feed into the raw material bin, and then discharge the feed from the raw material bin. Step 3, feed cooking: the mixed raw material is discharged from the raw material bin into the cam rotor pump, and then the cam rotor pump transports the feed to the cooking line, and the feed is transported on the cooking line, and steam is passed through the cooking line to implement continuous through-type cooking; Step 4, after the cooking is completed, hot feed is obtained, and the hot feed is loaded into the vacuum cooling equipment for cooling to obtain feed. The cooking method sets up vacuum cooling separately, and has the following defects: 1. After the feed is cooked, it needs to be barreled first, and then put into the vacuum cooling equipment for cooling, which affects the production efficiency; 2. An independent vacuum cooling equipment needs to be set up, the equipment cost is high, and it occupies a large area. Utility Model Content
