Low-Temperature High-Humidity (LTHH) Thawing Machine for Industrial Meat Processing

▌Product Description

The Meatech low-temperature high-humidity (LTHH) thawing machine is a purpose-engineered thawing system for high-volume meat, poultry, and seafood processors who need to thaw frozen raw material without the drip loss, cell damage, and colour deterioration that conventional thawing methods cause. As one of the core technology platforms behind Meatech's full industrial thawing machine range, the LTHH system circulates precisely controlled, humidity-saturated air around the product load — slowly and evenly raising core temperature from frozen to a controlled 0-4°C target, rather than shocking the product with direct heat or water contact.

Unlike room-temperature thawing, water-immersion thawing, or thawing tunnels without humidity control, the LTHH system holds temperature to ±1°C and relative humidity to ±5% RH throughout the full cycle — the combination that keeps surface moisture from evaporating away from the product while it thaws, holding water loss and drip loss below 1%. This is the same discipline that makes Meatech's equipment, across its entire thawing machine and thawing system lineup, a reliable choice for facilities that cannot tolerate weight loss or quality drift between batches.

Multi-chamber tunnel and vertical batch configurations scale the LTHH thawing machine from smaller processing lines up to full industrial throughput. Chamber count is not fixed — it is configured to your required production capacity, with each chamber independently controlled so a facility can run different products, batch sizes, or staggered load/unload schedules across chambers without one configuration compromising another. Full SUS304 stainless steel construction — including all food-contact surfaces — meets HACCP requirements and tolerates continuous wet-environment operation and high-pressure washdown.

▌FAQ

Q: How is a low-temperature high-humidity thawing machine different from a conventional thawing room or water bath?

A: A conventional thawing room without humidity control lets surface moisture evaporate as the product warms, producing drip loss and surface drying; water-immersion thawing avoids evaporation but risks water absorption and weight distortion, and is harder to hold at a precise, food-safe temperature. The LTHH system controls both temperature and humidity together — ±1°C and ±5% RH — so the air around the product stays warm enough to thaw evenly but saturated enough that moisture stays in the product rather than evaporating into the chamber, without any direct water contact.

Q: How many chambers does the multi-chamber tunnel configuration have, and can they run independently?

A: Chamber count is not fixed — it is configured to match your required production capacity, so smaller lines may run fewer chambers while high-volume lines run more, all within the same LTHH platform. Each chamber is independently controlled for temperature, humidity, and cycle timing, allowing different products, batch sizes, or staggered load and unload schedules to run across chambers within a single equipment footprint, without one chamber's cycle interfering with another.

Q: What products is LTHH thawing best suited for, compared to radio frequency (RF) thawing?

A: LTHH thawing suits large-batch, quality-priority thawing across almost any frozen meat, poultry, or seafood format, and is the more common choice for most production volumes due to its lower equipment cost and simpler operation. RF thawing uses electromagnetic energy to heat product from within and suits high-throughput lines where thaw speed is the priority. Many facilities run LTHH for the majority of their thawing volume and reserve RF for specific bottleneck stages.

Q: What food safety certifications does the machine meet?

A: The machine is manufactured from SUS304 stainless steel throughout, with all food-contact surfaces meeting HACCP food safety standards. It is also designed for easy dismantling and high-pressure water-gun cleaning between production runs.
