Zhucheng INNOTECH Freeze-Drying Technology Leads The Upgrade Of The Pre-Prepared Food Industry. The Fresh-Keeping Solution Solves The Problem Of Nutrient Loss In Ready-To-Eat Bird's Nests

Zhucheng INNOTECH Machinery Co., Ltd.

[Fujian Xiamen News] At the opening ceremony of the 2025 Asian Healthy Food Expo, Shandong Zhucheng INNOTECH Machinery Co., Ltd. released the "Ready-to-eat Bird's Nest Freeze-Drying Fresh-keeping Technology Solution". This solution uses the segmented vacuum gradient drying technology innovation to increase the retention rate of sialic acid, the core nutrient of bird's nest, to 96.7% (the traditional hot drying process is only 62%), officially opening the era of technological innovation of "zero-additive preservation" for high-end ready-to-eat tonics.

1. Three breakthrough highlights of the technical solution
▶ Nutritional activity dual-dimensional guarantee system
The -35℃ deep freezing process uses micron-level ice crystal control technology to accurately avoid the destruction of the bird's nest fiber structure. The protein denaturation rate is reduced by 82% compared with the traditional process; the intelligent regulation of water activity makes the moisture content of the finished product ≤3% (national standard ≤8%), and the rehydration ratio reaches 1:9 (industry average level 1:6), achieving the quality restoration of "freeze-dried and fresh".

▶ Intelligent flexible production system
The modular fast switching design supports one-click switching of multiple categories such as fruits and vegetables/meat/seafood, and the production line adjustment time is compressed to less than 1.5 hours; the AI ​​machine vision sorting system is equipped with dual-spectrum detection technology, with an impurity removal accuracy of 0.1mm and a raw material loss rate controlled below 0.8%.

2. Market application authoritative data confirmationCommercial cases from January to June 2025 show that the average price of freeze-dried bird's nest products is 45 yuan/g higher than that of traditional hot-dried products, and sales in the Southeast Asian market have increased by 220% year-on-year (traditional craft products only increased by 35% during the same period). In terms of green production indicators, unit energy consumption has dropped to 1.1kWh/kg, a 33% decrease from traditional equipment (traditional equipment energy consumption is 1.6kWh/kg).

3. Freeze-drying technology universal plan launched
In order to promote the technological upgrading of small and medium-sized food companies, INNOTECH officially launched the "Freeze-drying Technology Sharing Ecological Plan", providing light asset operation solutions and full-cycle technology empowerment, opening freeze-drying process open classes on the 15th of each month (the first phase attracted 87 companies to sign up), and simultaneously opening the cloud process database.

Industry analysts pointed out that this technological breakthrough not only reshaped the production standards of high-end tonics, but also lowered the industry's technical threshold through the equipment sharing model, and is expected to drive the annual growth rate of the pre-prepared food market to more than 18%.
