真空冷却知识库 · 智能问答
基于源鲜机械产品与技术知识库的智能助手，可就果蔬真空预冷、食品真空速冷、真空冻干等设备选型与原理提问。
知识库覆盖范围
本页是东莞源鲜机械（Dongguan Yuanxian Food Machinery Co., Ltd.）公开的真空冷却技术知识库问答入口，内容包括三条产品线的设备资料与配套技术文档：
- 果蔬真空预冷机：常温果蔬 25~30℃ 的快速降温工艺、批重与卡板配置
- 食品真空速冷机：熟食 80~90℃ 高温入料的两段式降温、真空系统与制冷配置
- 真空冻干机：预冻、升华干燥与解析干燥的参数与腔体配置
配套内容覆盖真空系统（水环泵 / 旋片泵 / 罗茨泵选型）、制冷系统、箱体与控制系统，以及选型问答与常见故障处理。可以直接提问，例如：“3 吨樱桃该选什么型号”、“真空预冷和冷库预冷差在哪”、“速冷后失水率怎么控制”、“冻干机共晶点怎么看”。
What this knowledge base covers
This page is the public AI knowledge-base entry of Dongguan Yuanxian Food Machinery Co., Ltd. It covers three product lines and the supporting technical documentation:
- Vegetable vacuum cooler — rapid cooling of fresh produce from 25~30°C, batch weight and pallet configurations
- Food vacuum cooler — two-stage cooling of hot food loaded at 80~90°C, vacuum pump and refrigeration configuration
- Vacuum freeze dryer — pre-freezing, primary and secondary drying parameters and chamber design
Supporting topics: vacuum systems (water-ring / rotary-vane / Roots pump selection), refrigeration systems, chambers and controls, plus selection Q&A and troubleshooting. Ask directly — for example: which model for 3 t of cherries, vacuum cooling versus cold-room cooling, controlling weight loss after cooling, or how to read the eutectic point of a freeze dryer.
