Equipment should comply with the provisions of this standard and be manufactured according to drawings and technical documents approved by the prescribed procedures. JB/T5683-1991
Equipment should comply with the relevant provisions of GB5083 and GB4064 to ensure the safety of users and convenient operation. 3.1.2
Each machine should be designed and installed in the specified position according to the equipment plan, and should meet the installation technical requirements of each machine; the connection between each machine and the foundation or base, bracket, and the connection of all supporting and auxiliary devices and pipes should be firm and reliable. 3.1.4 The machine runs smoothly, without abnormal noise, and the adjustment is flexible and accurate. Parts and components that need to be disassembled and replaced should be easy to disassemble and assemble. Various reversing devices should have clear azimuth marks, and directional rotating parts should have obvious rotation direction marks. 3.1.5 The equipment must be easy to clean, and there should be no dead corners where residual seeds cannot be cleaned on the route where seeds are processed. 3.1.6 The drying equipment and the combustion furnace should have fire isolation facilities or explosion-proof devices and be equipped with fire-fighting equipment. There should be reliable temperature control devices to ensure that the seeds are not damaged during the drying process.
3.1.7 During the operation of seed drug treatment machines, coating machines, pill making machines and other machines, the amount of harmful substances released shall not exceed the provisions of TJ36; machines that use highly corrosive substances such as sulfuric acid and hydrochloric acid to treat seeds should be closed or operated remotely. 3.1.8 The electronic control system should have overload protection and grounding devices. 3.1.9 The paint of the equipment should meet the quality requirements of ordinary weather-resistant coatings in NJ/Z3. 3.2 Technical indicators
The quality of seeds processed by the equipment and the comprehensive indicators of the equipment should meet the requirements of the following table. Approved by the Ministry of Machinery and Electronics Industry on September 13, 1991 and implemented on July 1, 1992
