Problem with soda ash chunks during production (English)
Abstract [sv]

Ett företag beläget i Västra Götaland tillverkar olika typer av en livsmedelsprodukt som säljs över hela världen. Produkten innehåller flera olika ingredienser och ingen process är den andra lik. Processen beror bland annat på sort och smak. Under processen tillsätts bland annat salt, vatten och smakämnen.

Natriumkarbonat, eller soda som det även kallas, är ett salt som tillsätts för att bland annat agera som konserveringsmedel. Natriumkarbonat som tillsätts kan bilda klumpar under processen och orsakar problem och produktionsbortfall under senare processteg. I samband med detta problem tvingas operatörerna att genomföra extra arbete som tar tid. Det förekommer bland annat reklamationer från konsumenterna. Syftet med detta arbete är att ta reda på varför dessa klumpar uppstår, samt diskutera lösningar på problemet. Olika parametrar undersöktes och uteslutningsmetoden användes för att hitta orsaken bakom problemet. Företagets avvikelsesystem studerades, processer följdes och jämfördes, och personal intervjuades för att ta fram data och material som behövs.

Reaktorerna där materialet blandas, värms upp genom att ånga tillförs till reaktorns innehåll, vilket innebär att temperaturen i reaktorerna är hög. Resultatet visar att dessa klumpar uppstår mest troligt på grund av den höga temperaturen i reaktorn kombinerat med metoden för hur natriumkarbonat tillsätts.

Abstract [en]

A company located in Västra Götaland produces a product that is classified in food industry and sells globally.

The product contains a variety of ingredients and no process is similar to the other. The process is determined by inter alia product type and flavor. During this process, salt, water and taste enhancers are added.The salt, specifically sodium carbonate, also known as soda ash, is used to prevent the product from rotting for instance. This addition of sodium carbonate can form chunks during the process and causes various problems and production loss later in the process. This causes extra work for the operators which takes time. Furthermore, it creates complaints from the consumers.

The goal of this paper is to find out why sodium carbonate chunks develop and discuss solutions to the problem. Different parameters were analyzed and the elimination method was applied in order to find the cause for the problem. The company’s deviation system was studied, processes were followed and compared, and process operators were interviewed for collecting necessary data and material.

The reactors, where the material is being mixed, are heated by adding steam to the mixture. Therefore, the temperature in the reactor is usually high. The result shows that the high temperature in the reactor combined with the method used to add the sodium carbonate is the reason behind the problem.
