Patent MY-197160-A (MY)
Title: Feed fermentation device
Inventor: JUN PAN
IPC: G01D21/02
Filed: 2019-02-01
Abstract: The present invention relates to a feed fermentation device, comprising a fermentation barrel, a gas discharge pipe, a liquid storage tank, a pH measuring component and a controller. The feed to be fermented is charged into the fermentation chamber of the fermentation barrel through a charging hole. The first detecting element of the pH measuring component extends into the liquid storage tank and contacts the absorption liquid in the tank. The controller is disposed on the fermentation barrel. The first detecting element is electrically communicated with the controller. When the gas generated from the fermentation of the feed in the fermentation chamber enters the liquid storage tank through the gas discharge pipe, the absorption liquid in the liquid storage tank absorbs the gas and gradually becomes acidic. The first detecting element transmits the detected pH value of the absorption liquid to the controller. When the first detecting element detects that the pH value of the absorption liquid has decreased to a predetermined value, the fermentation of the feed in the fermentation chamber is completed. The above feed fermentation device can effectively determine the completion status of the feed fermentation. The following circumstances can be avoided: the barrel lid is prematurely opened while the feed fermentation has not completed, or the fermentation time is too long. Therefore the production efficiency of the fermented feed can be effectively improved.  Figure 1.
