GAS HIGH-EFFICIENCY AND CYCLIC AMMONIA REMOVAL, APPARATUS FOR
CLOSED MEAT PRODUCT FERMENTATION WORKSHOP
The present disclosure relates to the gas ammonia removal technical field of closed meat product fermentation workshops, in particular to a gas high-efficiency and cyclic ammonia removal ap- paratus for a closed meat product fermentation workshop.
During the fermentation process of meat products, polypeptide and amino acid, formed by myoglobin degradation, may be subjected to decarboxylation through the action of amino acid decarboxylase generated by fermenting microorganism, so biogenic amine is formed, the content of the biogenic amine increases, and the accu- mulation of the biogenic amine will increase the quality safety risk of the fermented meat product. During fermentation, the gen- erated biogenic amine, peptide and amino acid may also occur a non-oxidative deamination reaction under the action of enzyme (hy- drogenase, hydrolase and the like) generated by the fermented mi- croorganism, so as to generate ammonia gas, water and hydrogen peroxide, thereby controlling the accumulation of the biogenic amine to a certain extent.
However, the continuous generation and accumulation of the ammonia gas are not conductive to the fermentation of the meat products, with irritation on human skin mucosa. The ammonia gas will react with water vapor in a high humidity environment to form ammonia water, which is adhered to surfaces of equipment and meat products, so that the local pH value of the product is affected, and the service life of the equipment is shortened.
The existing ammonia recovery technology is mainly applied in machinery, chemical engineering, electronic, cultivation, dung disposal and other fields. The equipment is relatively simple and has a low ammonia recovery efficiency, the gas cyclic utilization in the closed fermentation workshop cannot be realized, and using and sanitary conditions are not suitable for the technical field of food processing and safety control.
The purpose of the present disclosure is to provide a gas high-efficiency and cyclic ammonia removal apparatus for a closed meat product fermentation workshop, the ammonia removal in the closed meat product fermentation workshop can be realized and the gas after removing the ammonia may enter the closed meat product fermentation workshop for recycling. The gas can enter a spiral draft tube quickly by setting a booster pump and the spiral draft tube, and a gas inlet speed can be balanced and isotonic discharge can be realized through a design that the quantity of air holes increases successively along an air inlet direction and the hole diameter increases successively. A contact area between the gas and the liquid increases by designing an atomizer, so as to im- prove the reaction efficiency and the ammonia removal rate.
In order to solve the above technical problem, the present disclosure provides a gas high-efficiency and cyclic ammonia re- moval apparatus for a closed meat product fermentation workshop, including an ammonia removal tower, where a liquid storage tank is arranged above the ammonia removal tower, a liquid inlet at a top of the ammonia removal tower is equipped with an atomizer, and the atomizer is connected to the liquid storage tank through a liquid inlet pipeline; a spiral draft tube is arranged in the ammonia removal tower, one end of the spiral draft tube is connected to an air outlet of the fermentation workshop through an air inlet pipeline while the other end is connected to an inner wall of the ammonia removal tower, air holes communicating with an interior of the ammonia re- moval tower are formed in the spiral draft tube, and the quantity of the air holes successively increases along an air inlet direc- tion and the hole diameter also increases successively; and an air inlet check valve and a booster pump are arranged on the air inlet pipeline, one side of the top of the ammonia removal tower is equipped with an air outlet, the air outlet is connected to an air inlet of the fermentation workshop through an exhaust pipeline, a liquid outlet at a bottom of the ammonia removal tower is equipped with a liquid outlet pipeline, the liquid outlet pipe- line is connected to a circulating pipeline through a three-way valve, a liquid pump is disposed on the liquid inlet pipeline, and the liquid pump is connected to the circulating pipeline.
Further, an exhaust check valve and a gas purifier are ar- ranged on the exhaust pipeline.
Further, a liquid inlet check valve is disposed on the circu- lating pipeline.
Further, an ammonia detector is also arranged on the exhaust pipeline, and closed to the air outlet.
Further, the circulating pipeline is fixed together with the ammonia removal tower through a support.
Further, an outlet end of the liquid outlet pipeline is con- nected to a liquid collecting tank.
The present disclosure has the following beneficial effects: 1. In the present disclosure, the ammonia removal in the closed meat product fermentation workshop can be realized and the gas after removing the ammonia may enter the closed meat product fermentation workshop for recycling, so the gas circulation in the closed meat product fermentation workshop can be realized. At the same time, the ammonia removal can promote the non-oxidative deam- ination reaction, reduce the accumulation of biogenic amine, and improve the quality safety of the fermented meat product. 2. The gas can enter the spiral draft tube quickly by setting the booster pump and the spiral draft tube, and the gas inlet speed can be balanced and the isotonic discharge of the gas in the ammonia removal tower can be realized through the design that the quantity of the air holes increases successively along the air in- let direction and the hole diameter increases successively. 3. A contact area between the gas and the liquid increases by designing the atomizer, so as to improve the reaction efficiency and the ammonia recovery rate. 4. The reacted solution enters the circulating pipeline from the liquid outlet through the design of the circulating pipeline, then the solution enters the ammonia removal tower through the at- omizer to react with the ammonia, so the effective utilization rate of the solution is improved. The concentration of the solu- tion increases, the solution of high concentration is discharged to the liquid collecting tank through the three-way valve to be used for other processes, and the resource utilization rate is im- proved. 5. The gas after removing the ammonia enters the closed meat product fermentation workshop again by setting the exhaust pipe- line and the gas purifier, in order to achieve the benign and green sustainable development of the industry.
