Food industry

The processes of the food industry place very high requirements on hygiene. IPTech sensors are the right “ingredient” for processing raw materials such as sugar or starch and for the production of beverages, dairy products or chocolate products.

Brewery

With their certified hygienic design and high cleanability, IPTech sensors are ideal for use in the brewing process. Whether mashing, fermenting, storing or filling: Level and pressure sensors ensure reliable processes and consistently high quality in the production of beer.

Beer tank

Level measurement in the beer tank

Application

During the brewing process, a thick layer of foam is always present in the beer tanks. Therefore usually two pressure transmitters are used for level measurement. One transmitter measures the head pressure, while the other at the bottom measures the total pressure. The level is precisely calculated from the differential between these two pressures. Hygienic process fittings are absolutely necessary for these sensors.

Homogenizer

Pressure measurement in a homogenizer

Application

In order to prevent the milk fat from settling on top of the milk, either just the cream or the whole milk is homogenised in the next step. This is where the cream or milk is pushed through micro-sized nozzles, which reduces the size of the fat globules and distributes them evenly in the liquid. The homogenised cream is then returned to the skimmed milk. Pressure in the feed line is monitored to control the homogenisation process. At the same time, pressure monitoring of the hydraulic oil ensures optimal control of the pistons.

Purified water is used for the CIP cleaning of the production equipment. This water is produced through filtration and distillation and then stored temporarily in tanks. Absolute sterility and cleanability are essential criteria for all device components that have direct contact to the medium. This also applies to the instruments for level and pressure measurement in the tank.

Cleaning agent storage tank

Level measurement and point level detection in the cleaning agent storage tank of the CIP system

Application

The cleaning of process equipment in the food industry takes place within the framework of validated “Cleaning in Place (CIP)” processes that ensure aseptic conditions in production tanks. Sodium hydroxide or concentrated acid are frequently used as cleaning agents, which are stored in the storage tank of the CIP system and diluted in the production vessel. Level measurement enables optimal storage of these cleaning agents. Point level detection serves as overfill and dry run protection.

Evaporator

Density and pressure measurement during spice slurry thickening

Application

In the production of spices, the spices are first mixed with water and oil to form a slurry. This is fed into an evaporator, where water is removed to turn it into a kind of syrup. The thickened spice syrup must have exactly the right density – so that it can be spread thinly onto metal sheets for oven drying, ready to be ground into powder. To ensure the optimal density of the spice syrup, it requires a continuous measurement during manufacture. The pressure in the feed pipe leading to the evaporator also requires careful monitoring to ensure a smooth-running production process.

Storage tank for liquid foodstuffs

Level measurement in storage tanks for liquid foodstuffs

Application

In the food industry, liquid media such as glucose, fruit juice or syrup must always be kept in stock. To get them ready for the production process, some liquids must be either pre-cooled or pre-heated, while still in the storage tanks. This is done by means of a water-filled ‘jacketed’ container wall that can be either cooled or heated. To ensure uninterrupted production, a reliable level measurement is essential.

Concentrator

Density measurement of tomato juice in a concentrator

Application

The so-called Brix value (expressed in Brix degrees) is controlled in a concentrator. This value indicates the proportion of solids in a liquid (density). A certain Brix value is required, for example, to produce an optimal tomato concentrate. The liquid circulates in a spiral tube, from which the concentrate is obtained. The liquid content is extracted via evaporation in a special chamber. Electronic differential pressure measurement ensures accurate density measurement.

Sugar vacuum pan

Level measurement in a sugar vacuum pan

Application

The process in a vacuum pan is designed to ensure the growth of sugar crystals. The syrup is cooked in a closed boiler with steam-heated tubes and the liquid is extracted. The intermediate product is magma, a mixture of crystal sugar and syrup. This mixture is then poured into a holding tank, the crystallizer. In the holding tank, the cooling and drying process creates a substance called massecuite, from which the sugar crystallizes. The level in the tank must remain constant, so a reliable level measurement is required here.
