In the industrial sterilization of vacuum-packed meat products, water immersion (double-layer water bath) retort machines have become essential for expanding production, reducing costs, and improving quality. With over 20 years of expertise and more than 7,500 units delivered globally, ZLPH Machinery's water immersion food retort machine stands out with three core advantages: "high capacity, water efficiency, and large-pouch compatibility," providing an efficient, safe, and eco-friendly sterilization solution for products like vacuum-packed ham, braised beef, and ready-to-eat duck necks.
The ZLPH Machinery water immersion retort canning machine features a unique "upper tank for heat storage, lower tank for sterilization" design. Hot water is preheated and rapidly fills the sterilization tank, reaching the target temperature in 8–15 minutes. This high starting point and rapid heating enable a single-batch processing capacity over 30% greater than traditional spray retort machines.
1. Large Processing Capacity – Doubles Single-Batch Output
This retort packaging machine can easily meet the daily production demands of meat processors of all scales due to its significantly enhanced per-cycle throughput.
2. Saves Water & Energy – Directly Lowers Operating Costs
The equipment automatically recovers post-sterilization hot water to the insulated upper tank for reuse in the next batch. This efficient recycling system substantially reduces water and energy consumption.
3. Designed for Large Vacuum Pouches – Uniform Sterilization, No Cold Spots
For various aluminum foil vacuum bags, ZLPH Machinery employs patented "flow switching + tray distribution" technology. Multi-directional water circulation ensures even heat penetration, eliminating cold spots. A gentle, rapid cooling system prevents thermal shock, avoiding wrinkles or breaks—ensuring a smooth appearance and extending shelf life beyond 12 months.
4. Intelligent Control – Ensures Consistent, Repeatable Quality
The retort food machine features programmable temperature/pressure curves (±0.5°C, ±0.05 bar accuracy) and stores hundreds of recipes. Real-time F₀ value recording and cloud monitoring guarantee consistent sterilization across shifts, simplifying compliance with FDA, USDA, and domestic SC certifications.
5. Modular Design – Scalable for Future Growth
ZLPH Machinery offers flexible configurations—single units, dual parallel systems, or fully automated loading/unloading lines. Users can start with one retort machine and seamlessly add another, sharing components like hot water tanks and conveyors without wasting initial investment.
From resource efficiency to flawless sterilization of oversized vacuum pouches, the ZLPH Machinery water immersion retort machine delivers measurable results: 30% higher output, 95% water savings, and 30% reduced steam consumption. It is the ideal choice for vacuum-packed meat producers transitioning toward intelligent, low-carbon, and large-scale manufacturing.
Salmon, tuna, sardines and other fishery products found in cans and pouches are becoming more prevalent onto our dinner plates.
For food processors who produce various sauces such as ketchup, mayonnaise, salad dressing and chili sauce, ZLPH provides shaking retorts that can move products in a reciprocating forward and backward motion...
ZLPH has provided many food manufacturing plants with water immersion retorts for sterilizing sausages, minces, meatballs, lunch meats, foie gras and other meat products packaged in flexible pouches and metal cans of more than 500g in capacity.
In general, baby foods are packaged in glass jars or stand up pouches. Typically, our rotary retorts are perfectly suited to process fruit and vegetable purees with high viscosity, the nutrients and taste of which can be well preserved.
