Embodiment 1
[0030] 25g of sodium alginate was dissolved in 5L of water, 500g of DHA microbial oil (Qingdao Youlan Biotechnology Co., Ltd.), and a water jet venturi tube (SSQ-125, 3mm nozzle diameter, 0.7m 3 / h flow rate) is connected with a miniature magnetic pump (MP10R, Shanghai Core Pump Valve Manufacturing Co., Ltd.) through a pressure-resistant vacuum tube, DHA grease is pumped into the inlet of the Venturi tube, and sodium alginate solution is sucked from the suction port of the Venturi tube (see figure 1 ), atomized wet microcapsules into 10L 1% CaCl 2 The capsule wall was solidified in the solution for 1 min. The cured wet microcapsule particles were centrifuged at 1500 rpm at low speed and washed with water, and then entered the fluidized bed (WBF1G, Changzhou Fanjun Drying Equipment Co., Ltd.), using modified starch as the embedding agent. Prepare dry microcapsule powder, spray 200g of modified starch by top spraying method, the inlet air temperature is 60°C, after embedding, us...
Embodiment 2
[0032] 250g of potassium alginate was dissolved in 5L of water, 100g of linseed oil (Inner Mongolia Hongjingyuan Oil Co., Ltd.), and a water jet venturi tube (SSQ-125, 3mm nozzle diameter, 0.7m 3 / h flow rate) is connected with a miniature magnetic pump (MP10R, Shanghai Coolui Pump and Valve Manufacturing Co., Ltd.) through a pressure-resistant vacuum tube. wet microcapsules into 10L of 0.1% CaSO 4 Carry out capsule wall solidification in the solution, solidification time 2min, the wet microcapsule particle after solidification is centrifuged at 1500 rpm at low speed, washed with water, enters fluidized bed (WBF1G, Changzhou Fanjun Drying Equipment Co., Ltd.), uses octenyl succinate Use starch as embedding agent to prepare dry microcapsule powder, spray 180g of octenyl succinic esterified starch into the top spray method, and the inlet air temperature is 70°C. After embedding, use 80°C hot air to dry to obtain the product, and the excess starch is fluidized The beds are recyc...
Embodiment 3
[0034] 100g of ammonium alginate was dissolved in 5L of water, and 166g of tuna oil (Taicang Nuoya Shengnuo Biotechnology Co., Ltd.) was prepared, and a water jet venturi tube (SSQ-125, 3mm nozzle diameter, 0.7m 3 / h flow rate) is connected with the miniature magnetic pump (MP10R, Shanghai Core Pump Valve Manufacturing Co., Ltd.) through a pressure-resistant vacuum tube, the tuna oil is pumped into the inlet of the Venturi tube, and the sodium alginate solution is sucked from the suction port of the Venturi tube (attached figure 1 ), the atomized wet microcapsules enter 20L 2% Ca(NO 3 ) 2 Carry out capsule wall solidification in the solution, solidification time 2min, the wet microcapsule particle after solidification is centrifuged at 1500 rpm at low speed, washed with water, enters fluidized bed (WBF1G, Changzhou Fanjun Drying Equipment Co., Ltd.), uses octenyl succinate Use starch as embedding agent to prepare dry microcapsule powder. Spray 600g of octenyl succinic acid es...
