Tomato Soup Powder

Tomato soup powder is acidic, strongly pigmented and hygroscopic — it stains equipment and cakes in humidity. Each of those three properties creates its own problem on the line. The acidity works on contact parts that were not specified for it. The pigment marks hoppers, augers, forming tubes and every surface the powder touches, and it carries over into the next product if the dosing group cannot be stripped and cleaned. The hygroscopic behaviour shows up as caking: the powder takes ambient moisture, forms lumps and loses what little flow it had. It is a non-free-flowing powder — it bridges over the hopper outlet and rat-holes instead of feeding by gravity, and its bulk density shifts with standing time and with how much moisture it has picked up. Fines lift as airborne dust during filling and settle on the sealing area, where a thin film of powder is enough to leave a channel in the seal. Dosing therefore has to be positive rather than gravity-fed, which is why a tomato soup powder filling machine is built around an agitated auger. A servo-driven auger meters by rotation, so the dose comes from a counted number of turns rather than from the product flowing on its own, and the agitator in the hopper keeps the powder moving and breaks bridges before they form. Screw geometry and tube diameter are matched to the blend, because a coarse spray-dried base and a finely milled one do not behave the same way at the same setting. Volumetric cups are avoided here: they depend on consistent bulk density and free flow, and this powder offers neither. Contact parts are specified for acid tolerance, and the dosing group is built to be dismantled for cleaning, so colour does not carry over. Three formats cover the category. Stick pack leads it — single-serve instant preparation, one stick to one mug or bowl, with no opened pack left behind to absorb humidity; a tomato soup powder stick pack machine is usually the first request from instant-soup brands. The sachet, three or four side seal, does the same portioning job in a wider, flatter pack, and a tomato soup powder sachet packaging machine suits foodservice portions, sampling and retail multipacks. For catering packs, refill sizes and industrial supply, VFFS pillow bags are used. In all three the barrier film is the point: aluminium-based laminate keeps light and moisture out and holds colour and aroma in the pack. Dose is set by the serving rather than by the machine — a mug portion for stick pack and sachet, larger fills for pillow bags — and the auger and tooling are sized around the recipe you supply. Output should be read the same way. A stick pack or sachet machine runs several lanes side by side, and how many lanes fit follows the pack width: narrow sticks allow more lanes across the same web, wider sachets fewer. Packs per minute is therefore cycles multiplied by lanes, and a cycle figure on its own says nothing about output. On a VFFS the bag is formed one at a time, so cycles are bags. Send pack dimensions and target output and the configuration is sized to them. Mentpack builds the corresponding tomato soup powder packaging machine configurations: multi-lane stick pack machines, multi-lane sachet machines and VFFS systems, each with an agitated auger dosing group, acid-tolerant contact parts and dust control at the fill point. The specific model follows once format, pack width and required output are known. Typical customers are dry soup and culinary powder producers, instant food brands, private-label packers supplying retail chains, and foodservice suppliers packing portion-controlled servings for hotels, canteens and catering. The same configuration is generally used for the neighbouring products in a soup plant — cream soup bases, bouillon and seasoning blends — so a line specified for tomato soup powder usually covers a wider recipe list.
