Installation Project of Full-Process Processing Equipment for Apple Freeze-Dried Crisp Chip Food

Project Name: Apple Deep Processing Food Freezing Tunnel Installation Project by Zhongwei Shapotou Apple Industry Comprehensive Service Center, operated by Zhongwei Supply and Marketing Group Co., Ltd.

Completion time: December 2024, China Ningxia Zhongwei City.

Project Overview: Installation of a 4-ton/hour rapid-freezing tunnel and supporting refrigeration units. Apple deep-processing equipment includes: 1 set of ice-water cooling system, vibrating water drainage machine, hoist, vibrating distributor, 10 units of integrated apple peeling and slicing machines, 2 units of non-destructive apple scrubbing machines, and 2 units of 1500kg apple slice vacuum freeze-drying equipment.

The Apple Deep Processing Food Freezing Tunnel Installation Project, developed by Zhongwei Supply and Marketing Group Co., Ltd. and Zhongwei Shapotou Apple Industry Comprehensive Service Center, is a key industrial support initiative in collaboration with national government departments. This project fulfills critical missions: enhancing the regional apple deep processing industrial chain, increasing the added value of specialty agricultural products, and advancing rural revitalization strategies. As a flagship government cooperation project under NEW BEYOND ENVIRON, it has adhered to core principles of "national standards, strict full-process control, and high-quality delivery" since inception. With equipment selection, construction techniques, and quality acceptance all meeting industry-leading standards, the project aims to establish a replicable and scalable demonstration model for agricultural product deep processing equipment installation.

This project focuses on the precise installation and system debugging of equipment throughout the entire apple freeze-drying processing chain. It establishes a complete processing system centered around the production process of freeze-dried apple slices, with installation covering four core modules: pretreatment, rapid freezing, freeze-drying, and supporting refrigeration. The integrated equipment covers the entire process from raw material pretreatment to finished product freeze-drying. Key equipment includes a 1,500 kg vacuum freeze-drying system for apple slices and a 4-ton/hour rapid freezing tunnel. Both systems are high-end devices designed for large-scale apple deep processing, where installation precision directly determines product quality, production efficiency, and energy consumption control. These elements represent the core challenges and key difficulties in the project's construction.

The 4-ton/hour rapid-freezing tunnel, serving as the critical refrigeration facility for apple slice pre-treatment, prioritizes control of cooling efficiency and temperature stability during installation. Its positioning adheres to the principle of "proximity adaptation and ventilation cooling," minimizing transmission distance to subsequent freeze-drying equipment to reduce cold loss. Temperature sensors are precisely deployed within the tunnel and synchronized with the control system to maintain uniform temperature fluctuations within ±0.5°C, meeting the process requirements for rapid freezing and freshness preservation of apple slices. Concurrently, the integrated installation of the supporting refrigeration system—including core components such as the refrigeration unit, evaporator, condenser, and refrigerant piping—is completed to ensure efficient, stable, and energy-saving operation of the entire refrigeration system.

The installation of Apple pre-processing equipment serves as the foundational step in the entire workflow, encompassing the assembly and debugging of integrated systems for ice-water pre-cooling, material feeding and conveying, bubble cleaning, brush cleaning, peeling, and slicing. During installation, strict adherence to food processing hygiene standards is maintained, ensuring that all equipment contact surfaces are made of food-grade stainless steel to meet processing capacity requirements of 2-5 tons per hour. The electrical system installation follows the principle of separating power lines from signal lines, with all connections treated with waterproof insulation. Safety devices such as overload protection and leakage protection are integrated, fully complying with IP55 protection standards to balance operational safety and maintenance convenience.

As a government collaborative project, this initiative strictly implements the "Four Systems Management" requirements for infrastructure construction projects established by the National Development and Reform Commission (NDRC). It fully enforces the project legal person responsibility system, bidding and tendering system, engineering supervision system, and contract management system, incorporating mandatory safety and quality standards throughout the construction process. The construction team comprises a specialized technical unit staffed with certified refrigeration equipment installation engineers, electrical commissioning technicians, and safety supervisors. Critical procedures adopt a "dual-person verification and full-process documentation" system, while concealed works acceptance requires joint confirmation by the construction unit, supervisory unit, and government regulatory authorities before proceeding. Additionally, a comprehensive quality traceability system is established, with all equipment and components verified against product qualification certificates and test reports. Installation process documentation, commissioning records, and acceptance files are systematically archived to ensure full traceability and oversight of the entire project.

The successful implementation of this project will not only provide the Zhongwei Shapotou Apple Industry Comprehensive Service Center with deep-processing equipment meeting national standards, significantly enhancing local apple processing capacity and product quality, but also facilitate the transformation of Zhongwei apples from primary agricultural products to high-value-added processed goods. Furthermore, it will accumulate valuable experience for future government collaboration projects, establishing a benchmark model for coordinated government-enterprise efforts in rural industrial revitalization. After commissioning, the project will fully leverage its equipment performance advantages and technological leadership to inject strong momentum into the high-quality development of the regional apple industry.
