Currently, homemade fish meal is divided into three types: skim fish meal, semi-skim fish meal and whole fat fish meal. The output of skimfat fish meal is relatively low, the users are mostly small feed enterprises, large and medium-sized industries use less.From September to October, the oil content of raw fish is less. Although the fat of whole fat fish meal is similar to the fat of defat fish meal, whole fat fish meal has high yield and high profit, so many manufacturers mainly produce whole fat fish meal.After entering the winter, the fish body weight and fat are relatively increased, the oil content is also relatively high, some manufacturers have turned to produce semi-fat fish meal.
Degreased steam fish meal:
The production process of degreasing fish meal is to process the raw fish through cooking, pressing, solid-liquid separation, oil and water separation, drying, cooling, screening, crushing and a series of processes.
Semi-fat fish meal:
The difference between Semi-fat fish meal and semi-fat fish meal is that semi-fat fish meal passed through the fish oil separator machine, the separated water back into the fish meal drier, mixed with the fish powder to dry, increase the powder rate of fish powder, reduce the loss of muscle tissue.The smell of semi-and adigreated fish meal varies greatly, with a slightly rancid odor. The cost of hemifat is much lower than skim.
Whole fat fish meal:
The production process of whole-fat fish meal is that the fish is cooked by the fishmeal machine cooker, the fish and water go directly into the fish meal drier for drying, without pressing.Due to the semi-fat fish meal with raw fish freshness requirement is not high, fish oil content is very little, fat content of fat fish meal is relatively high, the shape of very thin acid price is relatively high, the salt content is relatively high, on the smell and fat fish mealr is very different, so the quality of relatively semi-fat fish meal is worse.
