DEVELOPMENT OF CARBOHYDRATE-VITAMIN-MINERAL ADDITIVES WET PRESSING WITH INCREASE IN MOLASSES CONTENT TECHNOLOGY

Abstract

A technology for wet pressing of carbohydrate-vitamin-mineral additives with increase in content of molasses was developed. In the UVMD wet pressing with increased molasses content two options for finished additives were considered: briquettes and pellets. In the first phase of work pilot batch of feed supplement for cattle was prepared: 25 % of rapeseed meal; 10 % of soybean meal; 4 % of feeding oil; 51 % of molasses; 5 % of lime; 5 % of premix. It is established that satisfactory mixing occurs when entering the molasses up to 40 %. Further increase in molasses content causes deterioration of mixing. In the second phase a research at the choice of materials, providing hardening of molasses briquette was carried out. At the same time additives for cattle contained 30 ... 50 % of molasses, sunflower meal, wheat bran, beet pulp, tricalcium phosphate, salt, premix. 3 % of hydrated lime and zeolite and also 5 % of limestone flour were used as the cementitious materials in the preparation of pellets with the molasses content of 40,0 %. Briquettes with 30 % and 50 % of molasses do not have sufficient strength. It has been established that when entering the 50 % of molasses and 3 % of hardeners countercurrent flow of material in the mixer stops, the mixture becomes viscous, of pasty consistency. Molasses briquettes had not hardened during storage, were soft and plastic. Briquettes containing 40,0 % of molasses and 3,0 % of hydrated or unhydrated lime were hard in comparison with briquettes containing other hardeners. With increasing input of hardeners up to 5 % molasses blocks were more solid and retained its shape.
