Abstract

The invention provides a high-protein microbiological feed and a preparation method of the high-protein microbiological feed. Dross is one of products produced in the process of floating and clarifying the mixed juice during sugar preparing by the sugarcane, and is rich in various organic non-sugar components; the dross is always considered as impurities and mixed in the mud juice by a sugar plant, and finally becomes lime sludge to cause waste. The preparation method provided by the invention comprises the following steps of taking the dross in the crane sugar plant as the raw material, and taking a non-protein nitrogen source, phosphate and magnesium salt and the like as the auxiliary materials; mixing the raw material and the auxiliary materials; sterilizing; adding beneficial zymocyte preparation; and fermenting at the aerobic condition so as to obtain the high-protein microbiological feed. By adopting the preparation method provided by the invention, the problems that a large quantity of dross is in the crane sugar plant and is adhered and hardly processed, and the loss of the sugar is serious can be solved well; and the current situation that the protein feed resources are in a shortage can be relieved. According to the preparation method, the cost is low, the period is short, the production technology is simple, the limitation from the field and equipment is less, and the quality and the yield of the high-protein microbiological feed are high, and the preparation method plays an important role in popularization and application of the mixed juice floating and clarifying technology in sugar plants.

Description

technical field [0001] The invention belongs to the field of resource environment and biological feed, in particular to a high-protein microbial feed prepared from sugarcane sugar factory scum as a main raw material and a preparation method thereof. Background technique [0002] Scum is a by-product of sugarcane sugar production. Due to the lag of relevant research, and the high viscosity and high humidity of scum itself, sugar factories have always regarded scum as an impurity. In order to recover the sugar in the scum as much as possible, the sugar factory usually mixes all the scum with all the sludge in the settler, and then filters it with a vacuum filter without filter cloth or a filter press, and finally becomes filter mud. [0003] Improving the comprehensive utilization efficiency of sugarcane sugar factory mixed juice scum and the quality of finished sugar are two major technical bottlenecks that the sugar industry has been facing for a long time. With the contin...
