Sauces, Purees, Oils and Prepared Foods
Food processing spans sauces and purees, edible oils, starches and sweeteners, prepared meals, protein solutions and plant-based products. What they share is difficulty: high viscosity, particulates and a strong tendency to burn on.
Free-Flow for solids. Anything carrying pulp, fibre, seeds or inclusions needs the open channel. A conventional plate pack will bridge and block, sometimes on the first run.
Hydrocooling for whole product. Where the product cannot go through an exchanger at all, a Temp-Plate bank floods it with chilled water instead, and the plates lift out for cleaning.
Surface temperature discipline. Using a cooler medium with more surface is almost always the right answer on food duty. It costs exchanger and saves cleaning downtime, and downtime is the expensive item.
Typical Specification
- Typical products: Sauces, purees, oils, starches, sweeteners, proteins
- Particulates: Free-Flow plate to around 3/8 inch
- Whole product: Temp-Plate bank assembly for hydrocooling
- Viscous streams: Plate turbulence at low velocity
- Fouling mechanism: Burn-on at the heating surface
- Medium strategy: Lower temperature, more surface
- Product contact: Type 316 stainless
- Cleaning: CIP and manual inspection
- Chilled water: Falling film chiller supply
- Allergen changeover: Frame opens for verification
Common FAQs
Move to the Free-Flow plate, which has a much more open channel and passes particles to around 3/8 inch. If the solids are heavier still, a Temp-Plate bank with removable plates is the next step.
Hydrocooling in a Temp-Plate bank. The product is flooded with chilled water kept cold by the plates, so it never contacts a heat transfer surface it could foul.
Surface temperature. Product against a wall well above its bulk temperature scorches and adheres, and the deposit insulates so the wall runs hotter still. A cooler medium with more surface breaks that cycle.
That is one of the strongest arguments for a gasketed frame. It opens completely, so every plate can be inspected and the changeover documented rather than assumed.
