Embodiment 1
[0013] The enterococcus faecium spray drying protection agent provided by the invention is composed of the following raw materials in parts by weight: 4-7 parts of soybean peptone, 5-7 parts of sorbitol, 3-6 parts of maltodextrin, and 1-3 parts of sucrose.
[0014] Enterococcus faecium spray drying method comprises the following steps:
[0015] ① Take the Enterococcus faecium concentrate prepared by liquid fermentation, add the above-mentioned Enterococcus faecium spray-dried protective agent, and mix evenly; the amount of the protective agent added is 13-23% of the mass of the bacterial concentrate;
[0016] ②Spray-dry the mixed bacterial liquid in step ①. The air inlet temperature in the spray dryer tower is 150°C~155°C, the temperature inside the tower is 80°C~95°C, the vacuum degree is -0.01 MPa ~-0.02MPa, and the outlet air temperature is 70°C~85°C.
[0017] The water content of the product after spray drying is less than 10%.
Embodiment 2
[0019] The enterococcus faecium spray drying protective agent provided by the invention is composed of the following raw materials in parts by weight: 50 kg of soybean peptone, 60 kg of sorbitol, 50 kg of maltodextrin, and 20 kg of sucrose.
[0020] Enterococcus faecium spray drying method comprises the following steps:
[0021] ①Separate 1,200 kg of liquid fermentation liquid containing Enterococcus faecium through a centrifuge to obtain 1,000 kg of bacterial concentrate; take a sample of 100 g to detect the content of live bacteria: 40 billion per gram;
[0022] ② Add 1000 kg of bacteria concentrate obtained in step ① to the mixing tank and add the above-mentioned Enterococcus faecium drying protectant and mix well;
[0023] ③Spray-dry the bacteria mixed liquid in step ②, the air inlet temperature in the spray dryer tower is 153°C, the tower inner temperature is 85°C, the vacuum degree is -0.02MPa, and the outlet air temperature is 80°C; 380 kg of spray-dried products are ob...
