example 1

[0015] a. remove excess moisture in the banana wine lees by centrifuge, and adopt hot air drying to dry it to a moisture content of 6%;

[0016] b. pulverize the dried banana wine residue, and pass through a 40-mesh sieve for subsequent use;

[0017] c. adjust the starch content of the material with cornstarch, the addition amount is 30% of the banana wine residue, and stir evenly;

[0018] d. Add water and mix well, adjust the moisture content to 18%;

[0019] e. Send it into a twin-screw extruder for puffing, processing and molding, the screw speed is 180rpm, the feeding speed is 30rpm, and the extrusion temperature is 125°C;

[0020] f. Packaging, dry storage.

Abstract

The invention discloses a method for producing extruded and expanded pet feeds by using banana lees. The technical scheme is that the method comprises the steps of: drying and crushing the lees, adding starch, adjusting water content, expanding and forming. By adopting the method, coarse fibers, proteins and minerals such as K, Na, Ca, Mg and the like in the banana lees can be recycled and changed into useful materials; by conducting extruding and expanding treatment, effects of processing and formation can be achieved at the same time, the coarse fibers and the proteins in the banana lees can be degraded and modified and the digestion, absorption and utilization ratio of the coarse fibers and the proteins can be improved; and the pollution to the surrounding environment can be eliminated or reduced. By using the banana lees to producing the extruded and expanded feeds, the effect of reusing the proteins, the starch and the dietary fibers is achieved, the nutritional components of the feeds are improved, the production process is simplified, the processing cycle is short and the economic efficiency is high.

Description

technical field [0001] The invention relates to a method for making pet feed, in particular to a method for making puffed pet feed with banana wine residue, which belongs to the field of agricultural and sideline product processing. Background technique [0002] Banana fruit wine is one of the main products of banana deep processing. In the process of banana fruit wine processing, whether banana juice or banana pulp is used for fermentation, after the wine liquid is separated, a by-product, banana wine residue, will be produced. Banana wine residue is relatively rich in nutrition, containing protein, carbohydrates, mineral elements, etc. If banana wine residue is not properly processed and discharged directly into the environment, not only the good resources will not be effectively used, but also the environment will be damaged. produce certain negative effects. If the banana wine dregs is reused, it will not only improve the utilization rate of resources, help to develop d...
