Continuous spice steam sterilization production line, producing 50kg to 4000kg per hour. Continuous production, can be connected with other upstream and downstream production equipment. First-in, first-out material conveying system ensures materials receive uniform sterilization treatment. Uses high-temperature steam for rapid sterilization, which can kill bacteria or microorganisms while minimizing the destruction of nutrients. Instant cooling system maintains product stability and safe packaging operations; it does not cause materials to undergo secondary drying due to increased moisture content. Entire process controlled by PLC, with a high degree of automation.
