Domestic leisure food equipment basically no density control measures, only in the spiral and puffing chamber configuration for simple considerations, some manufacturers copy Wenger's exhaust device, but due to some factors in technology and processing, maneuverability is poor. Leisure food equipment mechanical pressurized cutting is relatively easy to achieve, the available air pump to maintain the required pressure, discharge can be used off the fan, and because the required pressure is not high, the sealing of the moving parts is not too big a problem. The technology from the production of equipment, operation and use and density control of puffed products and other aspects of exhaust models are easier to realize, is currently the new direction of the development of puffing technology. Tempering technology is an indispensable part before puffing, the domestic research on the tempering device is still relatively in-depth, single-axis, double-axis have products. Density control in the production of expanded feed, especially aquatic feed production in the most challenging part, sinking feed should be basic in accordance with the desired way of sinking.

      The quality of leisure food equipment affects the quality and safety of production in the food industry, and the knives inside the leisure food equipment are in direct contact with food production and food packaging, so the selection of knives for leisure food equipment is very important. Selection of machinery should be tried to see the production, packaging out of the effect, the effect is only the quality, and durability, wear-resistant is not to try out, to the proof of time. The quality of snack food equipment affects the food industry production quality and safety, and snack food equipment inside the knife and food production, food packaging direct contact, so snack food equipment tool selection is very important. Selection of machinery to try to see the production, packaging out of the effect, the effect is only quality, and durability, wear-resistant is not to try to come out of the time to prove.
