How Leading Companies Benefit From TEWS.
The main applications of gelatin are in food, pharma, paper, etc., and it is beneficial for its thickening, emulsifying, binding, and adhesive properties.
A fast and highly accurate moisture measurement is important for all the applications of gelatin, which will allow complete control over the drying process.
Let's take a look at how TEWS inline solutions can support you.
Coming fresh from the field, Soya, Rapeseed/Canola, Sunflower oil seeds moisture levels are often too high, they need to be dried and well monitored before being stored in large silos for processing. The amount of oil obtained while pressed highly depends on the moisture content of the seeds or the beans.
TEWS solutions enable fast and accurate measurements of moisture and bulk density at many different positions in the entire process. TEWS instruments are industry 4.0 ready, and the data can be integrated into your digital process control systems.
Green coffee beans are having a typical moisture level of 11 – 12%. During the roasting of the coffee beans in a drum roaster a high temperature of ~ 230 °C will be applied. The well-known Maillard reaction will take place and the coffee develops its typical aroma. At the same time the moisture is significantly reduced. To assure that a pre-specified moisture level which might be a limit set by law (in Germany e.g. 5%) will not be exceeded the roasted coffee is measured right after the cooling stage using a process measurement system.
The harvest campaign of soybeans is 2 – 3 months/year whereas the processing takes place all year round. Therefore, the soybeans need to be stored in huge silos to enable a continuous production process. Coming fresh from the field the moisture level of soybeans is likely too high and therefore they need to be dried in large dryers before storage. In addition, it is a known fact that at a moisture level of 12% the soybeans will deliver the most oil during pressing. The TEWS microwave measurement is the optimum solution to make sure that the soybeans are dried to the setpoint for storing and to avoid over drying to be in best possible condition for the next processing step.
Einsatzmöglichkeiten - 100% Inline-Dichtemessung von Suppenwürfeln nach dem Pressvorgang zur Kontrolle des Zielgewichts von 4.000 mg / Würfel
Nutzen - Um ein Untergewicht der Suppenwürfel zu vermeiden, werden diese normalerweise mit einem leichten Übergewicht produziert. Vor der Anwendung der Mikrowellentechnologie überfüllte der Hersteller die Würfel um bis zu 5%. Mit einer Korrelation von 0,998 im Vergleich zu einer Waage, aber mit einer Geschwindigkeit von bis zu 20.000 Messungen pro Sekunde überwachen wir das Gewicht und konnten die Informationen an die Pressmaschine zurückgeben.
Durch die Kontrolle der Suppenwürfel und die automatische Steuerung des Pressvorgangs mit unserer Mikrowellentechnologie kann das Zielgewicht mit einer höheren Genauigkeit von 0,25% (+/- 10 mg statt vorher +/- 25 mg) erreicht werden.
Bei einer Produktion von ca. 150.000 Würfeln pro Stunde könnte man bis zu 30 kg Material pro Stunde sparen oder zusätzlich 7.400 Würfel produzieren. Bei einer Marge von 0,05 EUR pro Würfel und einer Produktionszeit von 15h pro Tag ergäben sich daraus Opportunitätskosten von 5.550 EUR pro Tag.
Crispbread is baked in a large oven and the product is coming out of the oven in 8 parallel lines. The operator selects 8 pieces of crisp bread to get a representative moisture result.
The measurement with a conventional halogen dryer takes 1 minute for sample preparation (milling) plus the measurement time of 8-10 minutes plus additional 1-2 minutes for recording and storing the data.
With the TEWS system, there is no need for sample preparation. The moisture readings are available within seconds and the data are stored automatically. Thus, for each measurement, the operator saves up to 10 minutes.
With 25 samples per day and 220 working days p.a., the savings sum up to 917 hours pa Assuming labour costs of only EUR 25 per hour the savings amount to EUR 22,917.
Moreover, the response time for controlling the oven is reduced which, in turn, allows for more efficient oven control.
Petfood safety and shelf life is as closely monitored as humans food is. Ingredients and formulas for cats and dogs food are various and they have been increased significantly lately, therefore the controls during the production processes are getting more and more important. Exactly like human food, the drying processes - that comes after the kibbles are extruded - are energy requiring and needs to be controlled precisely. Therefore the inline bulk density and moisture measurement before and after the dryer are crucial to fulfill the requirements and to keep the costs low. Microwave resonance technology is a very precise, reliable and cost effective measuring method for this application, it has been proven since decades and already installed in many production lines all over the world.
Water Matters.
Product quality and -efficiency can be significantly optimized by controlling the moisture content in almost all process steps. Managing the moisture of food and its ingredients is a key factor to achieve better results. TEWS patented solutions deliver high precision results. It's what matters when it comes to company goals and how to achieve them faster.
- Fast Inline Measurement – The continuous moisture measurement helps to cope with changing ambient process conditions and there is no need to wait long time on the results of spot checks.
- Product Quality – A precise moisture level is often decisive for the taste. And that, in turn, has an impact on the purchase decision of the end consumer.
- More Profit – Precise data of water content lead to precise prices.
- Energy Efficiency – Precise information about moisture allows optimization of drying processes, prevents overdrying and leads to lower energy costs.
- Storage Efficiency – Precise compliance with the recommended water content prevents mold, avoids fungal infection or early degeneration and increases shelf live.
It Takes Two.
TEWS patented two-parameter measurement solutions enable food producing companies to work with precise data in both ways at the same time. Data that relate to the moisture content of food and its ingredients as well as its density. Knowing the bulk density of food during the manufacturing process leads to even better results in terms of product quality and -efficiency.
- Mass Flow and Balance Check – Accurate density information being used to assure constant filling levels e.g. in bags and to avoid overfilling or to heavy products.
- Plant Efficiency – Fully automatic filling control of boxes and cartons up to 250 kg without manual efforts.
