Wuxi Shangde dryer Equipment Co., Ltd.'s Advantages in the Pet Food Protein Processing Industry
Wuxi (Sanling) Shangde dryer Equipment Co., Ltd., established in 2004, is headquartered in Wuxi Huishan Economic Development Zone. With a registered capital of 8 million RMB, it is a national high-tech enterprise and a specialized and innovative small and medium-sized enterprise. The company has over 20 years of experience in dryer equipment research and manufacturing, has obtained 12 utility model patents, and participated in the formulation of the industry standard "Technical Requirements for Animal Bone By-product dryer Equipment."
1. Core Technological Advantages
Full-process Technology Coverage:
Provides complete solutions from raw material pretreatment to product preparation.
Includes six core stages: raw material pretreatment (crushing and cleaning + high-temperature sterilization + classification), bone broth gradient boiling (enzymatic extraction of collagen), bone oil low-temperature pressing (deacidification, deodorization, and winterization), and bone meal ultra-fine grinding (micron-level + calcium and phosphorus fortification). Achieves a closed-loop treatment of "raw materials - products - by-products," with a resource utilization rate of over 90%.
High-efficiency dryer Technology:
High-speed centrifugal spray dryer achieves dryer speeds of 5-15 seconds, with continuous discharge, and uses "logarithmic spiral technology" to improve dryer uniformity by 20%.
The tube-type waste heat recovery device can reduce energy consumption by 20%, with a waste gas heat recovery rate of 35%-65%.
Safe and Compliant Design:
Equipment is equipped with customized explosion-proof/explosion-venting devices. Motors have double grounding, complying with food safety standards such as GB 14881 and feed safety standards such as GB/T 36195-2018.
2. Industry Applications and Market Performance
Professional Equipment Applications:
Provides specialized dryer equipment for pet food protein processing.
Equipment is adapted for special materials such as heat-sensitive substances (enzymes) and high-viscosity materials (bone broth extracts).
dryer recovery rate is over 98%, meeting the production requirements of high-protein pet food.
Market Coverage and Customers:
Serves over 200 cities nationwide, with over 1000 customers.
Collaborates with well-known companies such as Jinluo and Yangtze River Pharmaceutical.
Products are exported to international markets such as South Korea, Malaysia, and South Africa.
R&D Collaboration:
Collaborates with institutions such as Hefei University of Technology (Green Manufacturing Laboratory for Animal-Derived Foods), China Institute of Oceanography (Functional Food Raw Material Research and Development), and Jiangnan University (Straw Xylitol Extraction) on research and development.
3. Patent Innovation and Industry Standards
Patented Technology:
Holds 12 utility model patents, including the "High-Speed Centrifugal Spray Dryer".
Uses a "logarithmic spiral airflow distribution + aerodynamic optimization" design.
Innovative "low-temperature dryer + gradient heat exchange" scheme preserves food flavor.
Industry Participation:
