Problems solved by technology

This method is to process the feed into liquid feed, and achieve the purpose of killing African swine fever by heating and cooling the liquid feed, which can meet the needs of farms during use, but cannot meet the needs of feed manufacturers, and During the heating and cooling process, the cost will increase and the feed processing cycle will be too long

Embodiment 1

[0039] as attached figure 1 As shown, the heating tower 1 is the main equipment of the device, including a vertical tower with a rectangular cross section. The top of the tower is provided with a feed port 10 and the bottom is provided with a discharge port 22 . The heating tower 1 can be divided into a storage section 12 , a preheating section 13 , a heating section 15 , a cooling section 18 , a discharge section 20 , and a hopper 21 from top to bottom according to the working area.

[0040] Such as figure 2 image 3 As shown, in the middle of the preheating section 13, the heating section 15, and the cooling section 18, from top to bottom, rows of air inlet angular boxes 24 and air outlet angular boxes 26 are arranged horizontally and alternately in parallel. The angular box is made of thin steel plate, arranged in an inverted V shape, pentagonal, including two left and right slopes on the upper part and two left and right side walls extending vertically downward along th...

Embodiment 2

[0051] The device is equipped with a material level monitoring device 11 in the material storage section 12 of the heating tower 1, which monitors the highest and lowest material levels, and is linked with the feeding system outside the heating tower. When the raw material reaches the high material level, the feeding is automatically stopped; When the material level drops to a low material level, the feeding is automatically restarted to keep the raw material level in the storage section 12 at a suitable position.

Embodiment 3

[0053] Hot air and exhaust temperature and humidity monitoring devices are installed in each air chamber and air duct to monitor hot air and exhaust temperature and humidity online in real time. The monitoring signal is linked with the operation control of the hot blast stove 5. When the temperature of the hot blast is higher than the set temperature, the hot blast stove 5 automatically Reduce the amount of fuel, and the temperature of the hot blast decreases; when the temperature of the hot blast is lower than the set temperature, the hot blast stove 5 automatically increases the amount of fuel, and the temperature of the hot blast rises, thereby automatically adjusting the temperature of the output hot blast from the hot blast stove 5 to keep stable. The circulating hot air discharged from the heating tower 1 inevitably contains particles such as dust impurities, and the dust collector 6 is used to remove dust impurities in the circulating hot air.

Abstract

The invention provides a device and method used for killing African swine fever viruses in feedstuffs. According to the characteristic that the tolerance of the African classical swine fever viruses to heat is weak, hot air with relatively high temperature is utilized to heat the feedstuffs to certain temperature and heat preservation is performed for a certain period of time, and thus, the African classical swine fever viruses possibly present in the feedstuffs are quickly killed, and the operation of killing the African swine fever viruses can be rapidly implemented on the feedstuffs in timebefore the feedstuffs are delivered or after the feedstuffs arrive at the transportation destination. The device and the method have the characteristics of high feedstuff handling capacity, continuous handling process and low virus killing cost.

Description

technical field [0001] The invention relates to the field of detoxification, sterilization and epidemic prevention of feed raw materials, in particular to a device and method for killing African swine fever virus in feed raw materials. Background technique [0002] African swine fever is an acute and severe infectious disease of domestic pigs and wild boars. The mortality rate of sick pigs is high. The pig farming industry is extremely harmful. [0003] African swine fever is caused by the African swine fever virus. Its transmission routes include the transportation and distribution of live pigs and pork products and the sales and transportation of feed materials. The main raw material in feed materials is corn. When the feed raw materials contaminated by African swine fever virus in the epidemic area are sold and transported to the feed production plant for processing into finished feed products, the African swine fever virus in them cannot be killed, and can spread to var...
