Problems solved by technology

[0003] Liquid post-spraying is an effective way to solve the loss of heat-sensitive additives in feed processing, but there are still technical obstacles: post-spraying can only coat heat-sensitive additives on the surface of feed particles, which is easily affected by the environment, transportation and storage. The production process may also cause an increase in the pulverization rate of pellet feed

Embodiment 1

[0022] The screening of embodiment 1 compound protective agent and its influence on compound vitamin sedimentation rate

[0023] The raw materials used in the composite protective agent are seaweed powder, sodium alginate, and carrageenan, which are uniformly mixed according to different proportions and then added to the multivitamin. Use the following method to evaluate its performance: water solubility, take 12.5g of composite protective agent, put it in 1000ml water, stir at 100 rpm for 20min to mix, and compare the uniformity of mixing and the difficulty of dissolving in parallel. Viscosity, take 25g of compound protective agent, add 200g of compound vitamins and 2000g of water respectively, stir at 100 rpm for 20min and mix evenly, measure viscosity with NDJ digital display viscometer. Settling rate, start timing 0.5h after stirring evenly, observe the settling speed of the multivitamin solution and the settling rate after 12 hours, the good stability settles slowly and h...

Embodiment 11

[0027] Mix seaweed powder: sodium alginate: carrageenan evenly according to the weight ratio of 40:15:45 (formulation 1), take 12.5g of compound protective agent and put it in 1000ml water, stir at 100 rpm, the dissolution is slow and the water solubility is poor , after stirring for 20 minutes, there are obvious insoluble matter, which is in the form of agglomerates; take 25g of compound protective agent, add 200g of compound vitamins and 2000g of water, stir at 100 rpm for 20 minutes, and measure the viscosity to be 796mPa.s, the viscosity is too low, and the agglomeration will affect the spraying Atomization effect: After stirring evenly, the multivitamin solution began to settle slowly after 30 minutes, and the settlement rate after 12 hours was 15.3%.

Embodiment 12

[0029] Seaweed powder: sodium alginate: carrageenan is mixed evenly according to the weight ratio of 50:12.5:37.5 (Formulation 2). Take 12.5g of compound protective agent and put it in 1000ml water, stir at 100 rpm, the dissolution is slow, and the water solubility is good. After stirring for 20 minutes, there is a small amount of insoluble matter, which is in the form of small suspended lumps; take 25g of compound protective agent, add 200g of compound vitamins and 2000g of water, stir at 100 rpm for 20 minutes, and measure the viscosity to be 1075mPaf.s. The viscosity is low and does not affect the spray mist After stirring evenly, the multivitamin solution began to settle slowly after 40 minutes, and the settlement rate was 11.5% after 12 hours.

Abstract

The invention relates to the technical field of feed additives, and in particular to a protective agent specially used after aquatic feed spraying and application thereof. The protective agent is prepared from seaweed meal, sodium alginate and carrageenan, has certain adhesiveness, is good in dispersion performance, is capable of effectively maintaining uniform and stable distribution of a liquid thermosensitive feed additive before spraying and during a spraying process, and is convenient to use; after the spraying, the protective agent is capable of effectively adhering additives of vitamins and the like to the surfaces of feed particles, and the loss during transportation and feeding processes can be reduced, so that the cost of feed is favorably reduced, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a special protective agent for post-spraying of aquatic feed and its application in post-spraying of heat-sensitive feed additives such as vitamins and enzyme preparations. Background technique [0002] Large-scale production of pellet feed, extruded feed and expanded feed has become a development trend of the world feed industry. Feed mills increasingly use high-temperature short-time processing equipment such as granulators, extruders, deep conditioners, and general-purpose ripening granulators to perform conditioning, puffing, expansion, and granulation of compound feed. The high temperature treatment process can effectively kill some harmful substances such as Salmonella, reduce or inhibit anti-nutritional factors, and at the same time improve the palatability of feed and increase feed remuneration. However, in these processing techniques, due to the joint action of h...
