Embodiment 1

[0034] Such as figure 1 In, an automatic supply device for corn steep liquor in microbial fermentation production. Pump 1 is connected to storage tank 2 through feed pipe 519, storage tank 2 is connected to weighing tank 3 through weighing pipe 520, and weighing tank 3 passes ingredients The pipeline 521 is connected to the batching tank 4;

[0035] The storage tank 2 and the weighing tank 3 have a sealed structure. The storage tank 2 and the weighing tank 3 are provided with air inlet pipes, and the feed pipe 519, the weighing pipe 520, the batching pipeline 521 and the air inlet pipe are provided There are multiple valves. With this structure, accurate ingredients of corn steep liquor are realized, the quality of fermentation ingredients is improved, and labor intensity is also reduced. And because of the closed batching and transportation, the probability of corn steep liquor pollution is reduced.

[0036] In a preferred solution, the storage tank 2 is also provided with a co...

Embodiment 2

[0043] A method for batching using the above-mentioned automatic corn steep liquor supply device in microbial fermentation production includes the following steps:

[0044] 1. Use pump 1 to send corn steep liquor into storage tank 2;

[0045] 2. Use the air intake pipe of the storage tank 2 to pass compressed air into the weighing tank 3;

[0046] 3. After accurate weighing, use the air inlet pipe of the weighing tank 3 to pass compressed air into the corn steep liquor into the batching tank 4;

[0047] Through the above steps, the automatic supply of corn steep liquor in microbial fermentation production is realized.

[0048] In a preferred solution, the stirring device in the storage tank 2 is started every 4 to 8 hours and stirred for 10-20 minutes. After laboratory verification, the corn steep liquor solution will not produce precipitation and stratification within 8 hours. Therefore, the above-mentioned stirring scheme is adopted to avoid the precipitation and stratification of co...

Abstract

The invention relates to an automatic supply device and method of corn steep liquor in production of microbial fermentation. The automatic supply device is characterized in that a pump is connected with a storage tank through a feed pipeline, and the storage tank is connected with a weighing tank through a weighing pipeline; the weighing tank is connected with a mixing tank through a mixing pipeline, and the storage tank and the weighing tank are of sealing structures; air intake pipes are arranged on the storage tank and the weighing tank, and a plurality of valves are arranged on the feed pipeline, the weighing pipeline, the mixing pipeline and the air intake pipes. The method for mixing by the devices comprises the following steps: firstly, sending the corn steep liquor to the storage tank by the pump; secondly, introducing compressed air through the air intake pipe of the storage tank, and sending the corn steep liquor to the weighing tank; thirdly, after precisely weighing, introducing the compressed air through the air intake pipe of the weighing tank, and sending the corn steep liquor to the mixing tank. The automatic supply of the corn steep liquor in production of microbial fermentation is realized by the steps. The corn steep liquor can be automatically and precisely mixed by the device. After a batch of corn steep liquor is conveyed, the pipelines are conveniently cleaned, so that rancidity or infestation of residual corn steep liquor is avoided.

Description

Technical field [0001] The invention relates to the field of microbial fermentation production technology, in particular to an automatic supply device and method for corn steep liquor in microbial fermentation production. Background technique [0002] In the fermentation production of neomycin, corn steep liquor is used as an indispensable organic nitrogen source material for fermentation medium. With the continuous expansion of the scale of neomycin fermentation production, the existing operating method of using barreled corn steep liquor in actual production feeds is no longer suitable for production needs: [0003] 1. It is inconvenient to carry and operate. The barreled corn syrup is 240Kg per barrel, all of which are carried manually, which consumes more manpower and heavy physical strength. [0004] 2. The feeding operation is inconvenient. It takes 2 to 3 people to sample and weigh from the corn steep liquor barrel, and the corn steep liquor is scattered all over the ground a...
