Cause salmonella-polluted main cause to be: the pollution that raw material is brought by equipment and environment in process; The sanitary condition of packaging material is poor, the pollution that brings; Raw material and finished product are polluted in storage and transportation process.It is reported, U.S. CDC statistics, since in August, 2006,41 states of the U.S. have 329 people elder generation postoperative infection Tennessee type salmonella, and the arch-criminal is two sauce of cultivating peanut that Kang Nagela company produces.The salmonella epidemic situation is broken out again in the U.S. at the beginning of 2009, has 474 people and catches an illness, and causes 6 people dead, and US authorities suspects relevant with contaminated peanut butter food.The peanut produced of american peanut company is broken is subsequently detected salmonella by quick-fried again.In recent years, the peanut company of China also was detected salmonella repeatedly and exceeded standard, and had influenced the company's reputation and the market competitiveness greatly.

Summary of the invention

The objective of the invention is to kill the salmonella that possibly exist in the peanut raw material; A kind of broken production technology of peanut of controlling salmonella is provided; This technology utilization salmonella non-refractory, not anti-low humidity, the characteristics of lower oxygen concentration resistance environment not, design three big control salmonella steps, with peanut raw material through high-temperature steam processing, infrared sterilization (dry heating method), that anaerobic slice packaging automatic continuous production three big master operations are processed peanut is broken; Through this PROCESS FOR TREATMENT; Can make in the peanut crumble product no salmonella residual, improve security of products, strengthen the competitiveness of product in market.

The objective of the invention is to realize that by following technical scheme developed the broken production technology of peanut of control salmonella, the technical scheme that the present invention adopted comprises the steps:

1) impurity removing: remove mudstone, mould decayed fruit, glass impurities;

2) gold is visited and is sieved: the second removal raw material impurity, and, remove foreign matter according to unified standard removal peanut;

3) steam sterilizing: vapor (steam) temperature 80-90 degree, time 1-2 minute;

4) infrared sterilization: it's infrared sterilization machine 2-3 second is past product;

5) anaerobic slice packaging: utilize stainless steel material to carry out automatic continuous production.

The temperature of described steam sterilizing is 80-90 ℃, and the time is 1-2 minute.

Beneficial effect of the present invention: through high-temperature steam processing, infrared sterilization (dry heating method), anaerobic slice packaging automatic continuous production three big PROCESS FOR TREATMENT; Can make in the peanut crumble product no salmonella residual; Improve security of products, strengthen the competitiveness of product in market.And peanut is broken easy to carry, and keeping quality is strong, is a kind of nutraceutical with market potential.

Specific embodiment

The technical scheme that the present invention adopted comprises the steps:

1) impurity removing: remove impurity such as mudstone, mould decayed fruit, glass;

2) gold is visited and is sieved: the second removal impurities in raw materials, and, remove metallic foreign body according to the excessive too small fruit of unified standard removal;

3) steam sterilizing: vapor (steam) temperature 80-90 degree, time 1-2 minute;

4) infrared sterilization: it's infrared sterilization machine 2-3 second is past product;
