When a fire occurs in the barrel body 1, the fire-fighting steam valve is opened, a large amount of steam enters the inner cavity of the barrel body 1 from the fire-fighting steam port 1j, oxygen is discharged, open fire can be rapidly extinguished, and the safety production of equipment is guaranteed.

Taking 5000 tons/day soybean production line as an example, the content of organic impurities is about 0.25 percent, namely 12.5 tons/day, if the soybean meal is sterilized and added into the soybean meal for sale, the price of the soybean meal is 2800 yuan/ton, namely 35,000 yuan/day can be increased, if the soybean meal is produced for 300 days in a year, the annual income is increased by 10,500,000 yuan/year, and under the market environment with intense competition, the income brought by the organic impurities is still very considerable.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention. In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention. The undescribed technical features of the present invention can be realized by or using the prior art, and are not described herein again.
