▌ Solution Overview
Meatech's smoked and cooked meat processing line is built around a smokehouse designed to eliminate colour variability as a production problem. Three-dimensional hot air circulation maintains ±1 °C temperature uniformity regardless of product position in the load. Three smoking methods — wood chip, sugar, and liquid smoke — deliver consistent smoke exposure across every piece in the chamber. A 66-to-100 recipe library ensures every batch runs the identical thermal profile, regardless of operator. The line sequences curing injection, tumbling, filling (for sausage products), drying, and smoking into a single validated production system.
▌ Process Flow — Stage by Stage
Stage 1 — Curing: Brine Injection & Vacuum Tumbling
Uniform curing salt distribution throughout the product is as important to the final flavour and colour of smoked ham and bacon as the smoking stage itself. The brine injector delivers curing brine — nitrite salt, phosphate, and seasoning — directly into muscle tissue, ensuring consistent distribution from surface to centre. Vacuum tumbling for 4–8 hours completes protein extraction and brine redistribution, producing the consistent pink colour and water retention that define premium cured smoked meats.
Stage 2 — Filling (Sausage Products): Vacuum Stuffer & Tying Machine
For smoked sausage products, cured and emulsified paste is filled under vacuum to prevent air pockets, and segmented by the automatic tying machine before smoking. Vacuum filling is particularly important for smoked sausage — air pockets oxidise during the smoking stage, creating grey discolouration inside the sausage body that is visible on the slice face and rejected by both retail and food-service customers.
Stage 3 — Drying: Hot Air Circulation Oven
Surface moisture is removed in the drying oven before smoking — a step that is skipped in many smaller operations but is critical for achieving the deep mahogany colour characteristic of premium smoked meats. A dry surface absorbs smoke compounds far more effectively than a moist surface, producing richer colour development with less smoking time. The drying oven's programmable temperature-humidity curve is matched precisely to casing type and product geometry.
Stage 4 — Smoking & Cooking: Fully Automatic Smokehouse
The smokehouse executes the complete drying-smoking-cooking sequence in a single automated program. Three-dimensional airflow eliminates dead zones that cause colour variation between product positions. Smoke is filtered through multi-layer screens before entering the chamber, removing tar particles that would deposit as dark spots on product surfaces. Post-smoking cooking achieves the internal temperature required for food safety compliance — with the time-temperature log automatically recorded for HACCP documentation.
▌ Solution Highlights
› ±1 °C temperature uniformity throughout the chamber load — eliminates top-to-bottom colour variation
› Multi-layer smoke filtration — removes tar particles, prevents surface spotting
› Three smoking methods on one machine — wood chip, sugar, liquid smoke — for full product range flexibility
› 66–100 recipe programs — every batch runs the identical validated thermal profile
› Automatic time-temperature logging — HACCP documentation generated at end of each cycle
▌ ROI & Commercial Value
