Tomato Production
Autoclave
Food Industry
The aluminium cans are sterilised with steam at a temperature of 120 °C and a pressure of 3 bar in an autoclave. Then, while the cans are still in the autoclave, they are cooled down with water to a temperature between 35 °C and 40 °C. They are dried and further cooled before being stacked in the warehouse. To enable a safe, optimal autoclaving process, pressure and limit level are measured.
Concentrator
Food Industry
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.
Mixer
Food Industry
Foods often consist of a mixture of different raw materials. Mixers are used, for example, to mix solids into liquids. The resulting mixture is then further processed or used in downstream processes, if required, or directly packaged. The level switches are used to control the inlet valve and protect the vacuum pump from running dry.
Plastic tank for chlorides and salts
Food Industry
Sodium chloride and calcium salts are stored in small plastic tanks. When necessary, these substances are added to the food as additives to regulate the pH value and consistency. The plant operator needs exact level readings from the tanks at all times to ensure timely replenishment.
Rotary filling line
Food Industry
The selected, peeled tomatoes are packed in metal cans with a capacity of up to 10 kg. The telescopic filler automatically feeds the tomatoes into the cans. The level of the tomatoes on the turntable must be measured so that there are enough tomatoes to fill the cans.
Steam pressure peeler
Food Industry
The washed tomatoes are fed into the steam drum on a conveyor belt. They are first heated to about 115 °C. In the next process step, the tomatoes are cooled in a vacuum, which separates the skin from the tomato. The skins are transported to a container via a special conveyor belt and the peeled tomatoes go to the next process step. Pressure sensors measure the steam as well as the vacuum in the pipelines. Level detection is required to monitor the level in the waste container.
Supply tank of tomato filling machine
Food Industry
Tomatoes are stored in the supply tank of the filling machine. Reliable level measurement is important for an optimal filling process. A point level sensor is used to also prevent dry run.
Tank for pH value regulation
Food Industry
When correcting the pH value and adding ingredients; salt, sugar or citric acid are dissolved in water. Depending on the product, acids or bases are added to obtain the desired pH value in the final product. To ensure a continuous production process, reliable level measurement is required.
Tomato juice filling machine
Food Industry
The empty cans enter the filling machine on a conveyor belt. As soon as an individual can reaches the appropriate position for filling, it is pulled in with the help of a pneumatic cylinder and filled under vacuum with natural tomato juice. The level of juice in the supply tank is monitored by a radar sensor. In each filling cycle, the same amount of tomato juice is sucked out of the supply tank. Reliable point level detection ensures that all cans are filled equally.
Tomato juice heat exchanger
Food Industry
In the plate heat exchanger, the tomatoes are heated up to about +85 °C, depending on the product, so that all germs are killed. The tomatoes are heated in multiple sections, kept hot for a time and then cooled down again. This process is suitable for thermal treatment of tomato concentrate, pulp and juice. Reliable pressure measurement is required to maintain an optimal process in the heat exchanger.
Tomato pulper
Food Industry
In the pulper, the cores and skins are separated from the pulp of the tomatoes by means of centrifugal force. To ensure that this process runs efficiently and that there is no downtime, it is important to monitor the level precisely. Limit level detection in the waste container prevents overfilling.
Washing line
Food Industry
Tomatoes are unloaded from the truck into the basin and, with the help of water, pumped through the washing line. Heavy materials such as stones and mud sink to the bottom and are caught by a flow in the opposite direction. The tomatoes are washed with high-pressure air blowers. The radar sensor enables accurate level measurement, ensuring an optimal flow of tomatoes.
