CN2336579Y - Compound floating fish food - Google Patents

Abstract

The utility model relates to a compound floating fish feed, which has the floating performance of full puffing fish feed. The energy processing consumption is lower than the full puffing fish feed, high pressure and high temperature are not generated when the processing is conducted, some nutrients in the feed are less damaged, and thereby, the purpose of reducing feed production cost and improving feed efficiency can be achieved. The feed is heated and sprayed into bulky small rice grains or rice particles, the feed is embedded in soft feed materials which are kneaded with various feed raw materials, adhesive agent, additive agent, etc., and water and compacted into a belt shape, and then, the feed is formed by the press and paste, strip cutting, particle cutting and drying conducted by a roller.

Description

Compound floating fish food

The utility model relates to a kind of type of swimming fish meal of low processing cost.

At present, the floating fish meal of graininess all adopts expanded method to produce, and is exactly with pulverizing such as various raw materials, adhesive, additives, and after mixing by formula rate, forms through bulking machine is expanded.Its production principle is, mash feed pushes through screw rod, be subjected to high pressure and produce high temperature, starch composition in the raw material produces gelatinization, when from nib, being extruded, pressure descends suddenly and produces expanded phenomenon, feed forms the bulk body of cellular after expanded, thereby can float on the water surface, is a kind of fish meal commonly used, but the part that also comes with some shortcomings mainly is that power consumption of polymer processing is too big, and the 5-6 that normally processes plain particles shape feed doubly, and the high pressure-temperature that the time produced of extruding, elements such as the vitamin A in the feed, C are destroyed bigger etc.

The purpose of this utility model is: provide a kind of graininess compound floating fish meal, it not only has the performance of swimming of full expanded pellet diet, and power consumption of polymer processing is low, adds not produce high pressure-temperature man-hour, destroys less to elements such as the vitamin A in the feed, C.

The purpose of this utility model is achieved in that by feed formula; with various raw materials; adhesive; after additives etc. mix; add that an amount of water integrates into soft feed group's 1 usefulness extruser or oodle maker is made into continuous band-shaped soft feed; in the middle of the soft feed of two ribbons; evenly add small rice grain or the rice particle that is sprayed into bulk body through heat; then through a pair of cylinder roll extrusion; the soft feed of two ribbons is overlayed together; bulk shape small rice grain or rice particle in the middle of making embed in the soft feed; become a mixed feed band, again through slitting; pelletizing; dry and become the fish meal that can float on the water surface.

Because adopt such scheme, feed proportion reduces, so feed can get up at water float, compares with the method for producing floating fish food with bulking machine, has two big advantages at least, the one, the specific yield less energy consumption; The 2nd, less to element such as vitamin A, C destruction in the feed, thereby can reach the purpose that reduces the production of fodder cost and improve feed usefulness.

Further specify below in conjunction with drawings and Examples:

Fig. 1 is a process principle figure of the present utility model.

Fig. 2 is the profilograph of embodiment.

1 extruser, 2 banded soft feeds, 3 bulk shape particle distributors, 4 bulk shape particles, 5 overlay cylinder, 6 slitting cylinders, 7 cylinders, 8 mixed feeds, 9 mixed feed shells among the figure.

Among Fig. 1, the soft group of feed through about two extruseres (1) be extruded into two continuous band-shaped soft feeds (2), V-shaped angle is introduced a pair of cylinder (5) that overlays, bulk shape particle (4) under the simultaneously even spreading of bulk shape particle distributor (3), through overlaying overlaying of cylinder (5), bulk shape particle is embedded in the continuous band-shaped soft feed (2), be cut into the feed bar through a pair of slitting cylinder (6) again, be cut into mixed feed grain (8) through a pair of pelletizing cylinder (7) then, whole process is carried out synchronously.

In the embodiment shown in Figure 2, bulk shape particle (4) is embedded in the soft feed equably, through overlay, behind the slitting, pelletizing, the soft feed of both sides just becomes the mixed feed shell (9) that is wrapped in bulk shape particle (4).

Claims (1)

1. A kind of compound floating fish food is characterized in that: embedding in the middle of the feed granules has bulk shape particle.
