Small hydraulic power generator
Production Machinery Business (Labor-saving support)
Proposal and maintenance of various production machinery
We are quick to catch up with the latest information on cutting-edge equipment in Japan and around the world to contribute to labor saving and productivity improvement in food factories and make the optimal proposals. We build and follow up a meticulous maintenance system by taking advantage of our comprehensive capabilities.
Bone and Meat Separator (TAT master BFP)
- We can produce high-quality, manageable chicken minced meat from chicken bones.
- The main part is small and short, and conveyors are not required.
- It is a division of labor with two motors for cutting materials(extrusion)and minced (separating).
- Production speed depends on the amount of input raw materials.
- It enables flexible control of yield and quality.
- We will do perfect follow-up by specialized engineers.
Production speed
（１４００ｋｇ/Ｈ Yield rate：７２％）
Broiler chicken bone
（１８００ｋｇ/Ｈ Yield rate：６２％）
Chicken Trimming
（１６００ｋｇ/Ｈ Yield rate：７０％）
Manufacturing Development and Testing
We perform product development, product processing tests, and cooling tests using our demo equipment.
For customers who are unable to visit us in distant locations, we can also make video recordings and offer proposals remotely. We can also flexibly handle raw materials from receiving to procurement.
