[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] Before the feed is cooked, the dry powder needs to be mixed with water, and a mixer is needed at this time; however, the existing mixers require manpower when feeding and discharging materials, and the feeding and discharging efficiency is low, which affects the cooking efficiency and increases the workload of workers.

The steam control pipeline is sequentially provided with a stop valve 61, a filter 62, a first flange pipeline 63, a flow meter 64, a second flange pipeline 65 and a regulating valve 66 from the outside to the inside. The stop valve 61 is connected to the steam supply pipeline, which is used to open and close the pipeline to achieve the purpose of controlling whether steam is introduced. The inside of the stop valve 61 is connected to a filter 62, which is a U-shaped filter 62 for filtering foreign matter in the steam; the filter 62 is connected to the first flange pipeline 63, and the flow meter 64 is connected between the first flange pipeline 63 and the second flange pipeline 65. The flow meter 64 is a vortex flowmeter 64, which is used to detect the steam flow in real time, so as to facilitate the staff to adjust the appropriate steam flow according to the actual working conditions.
