Bulking agent for fermentation of organic fertilizer and preparation method of bulking agent

Abstract

The invention discloses a bulking agent for fermentation of an organic fertilizer and a preparation method of the bulking agent and belongs to the technical field of a fermentation bulking agent. The bulking agent is prepared from the following raw materials in percentage by weight: 25 to 35 percent of starch, 10 to 15 percent of calcium carbonate, 25 to 30 percent of ammonium bicarbonate, 5 to 15 percent of anhydrous potassium aluminium sulfate and 15 to 25 percent of mono calcium phosphate. In the preparing process of the bulking agent, each component raw material is sufficiently dried and ground and is sieved into fine powder by a 120-mesh sieving machine and then the fine powder is uniformly mixed and stirred for 20 to 30min in a stirring machine. The bulking agent has the benefits of improving a fermentation temperature of an organic fertilizer pile body, shortening fermentation time, shortening a matured period of each raw material, reducing mechanical overturning energy consumption and grinding energy consumption of the subsequent workshop section and the like.

Description

Technical field [0001] The invention relates to the technical field of fermentation bulking agents, in particular to a bulking agent for organic fertilizer fermentation. Background technique [0002] Aerobic fermentation is the core of the maturity of raw materials for organic fertilizer production. During the fermentation process, the raw materials undergo mineralization and humification, and are transformed into inorganic substances, small molecular organic substances and humus that are easily absorbed by plants. In actual industrial production, due to the influence of many factors such as the amount of raw materials, production costs, site and equipment, poor ventilation is inevitable, resulting in slow growth of the fermentation temperature of raw materials, low pH in the fermentation process, slow maturity, and longer fermentation cycles. In production, the main method to improve the aeration conditions of the fermentation reactor is to flip the stack. If the flip is not ti...

Problems solved by technology

In actual industrial production, due to the influence of many factors such as the amount of raw materials, production cost, site and equipment, poor ventilation is unavoidable, resulting in slow growth of raw material fermentation temperature, low pH in the fermentation process, slow decomposition, and longer fermentation cycle

In production, the main method to improve the aeration condition of the fermentation heap is to turn over the heap. If the turning is not timely, the heap will be in facultative or anaerobic conditions; if the turning is strengthened, the energy consumption will be too high and the production cost will be high
