Full-automatic shallow tray culture tray type solid fermentation device and control method

Abstract

The invention relates to the technical field of biopesticide on-line expanding culture devices, in particular to a full-automatic shallow tray culture tray type solid fermentation device and a control method. The device includes: an air compressor, an incubator body, a shallow culture tray and a PLC, and a humidity control system, a circulating temperature control system, a detection probe and an air mass flow meter which are connected with the PLC; wherein a detection probe and a plurality of shallow culture trays are arranged in the incubator body; the air compressor is connected with the incubator body through the air mass flow meter and the humidity control system in sequence; and the circulating temperature control system is connected with the incubator body. Technical parameters in the fermentation process are accurately controlled by adopting the dissolved oxygen electrode, the humidity electrode and the temperature electrode, the fermentation efficiency is high; meanwhile, the microbiological contamination rate is reduced by adopting jacket circulating water temperature control, 25-degree angle between the tray and the bottom plate of the incubator, external humidification design and the like, and the fermentation yield is improved.

Description

technical field [0001] The invention relates to the technical field of on-line expansion cultivation devices for biological pesticides, in particular to a full-automatic shallow-disc culture-disc-type solid fermentation device and a control method. Background technique [0002] Biopesticides mainly refer to the use of microorganisms and their metabolites to prevent and control crop diseases and insect pests. It is an important means of biological control. It has strong biological selectivity, is harmless to crops, humans and animals, has a direct killing effect on pathogens and nematodes, and has no pesticide residue after application. The main components of biological pesticides are bacteria and their metabolites. Such as Bacillus, actinomycetes, gibberellins and so on. [0003] my country is a big crop producing country, and a large amount of chemical pesticides are used for the prevention and control of crop diseases and insect pests. However, a large amount of chemical...

Problems solved by technology

The disadvantage of the device is that the condensed water in the temperature control layer will drip into the culture medium of the next layer during the fermentation process, and the local humidity is too high, resulting in fermentation failure. In addition, the temperature control method at the bottom of the culture layer occupies the cultivation space, which is not conducive to industrial scale-up.
