Complete Quality Control SystemA Solution for Filling for the Food Industry
Filling containers requires very fast, precise and repeatable results. Inconsistency in
weighing can be costly – either giving away product by overfilling containers or risking
fines by not meeting Weights and Measures standards or net weight legislations.
A large US pudding and yogurt manufacturer was facing this exact problem monitoring
their fill weights during packaging.

n Sanitary Equipment DesignFor Your Brand’s Reputation
Safety and integrity of your products is at the very heart of your brand’s reputation.
When sanitation practices are insufficient, bacteria can harbor and thrive in equip-
ment used in food processing. Also scales may harbor and transfer the bacteria to products.
When this occurs, scrupulous sanitation must occur to eliminate potential hazards.
Bothindustryandgovernmentarework-ing diligently to reduce the incidence ofbacteria’s such as Listeria in foods andpreventitsgrowthandspreadinfoodpro-cessing plants. Equipment is a potentialsourceofpathogengrowth–so is it thescale!Oneofthemostimportantfactorstoconsiderwhenbuyingscalesfortheuseinfoodprocessingaredesignandconstruc-tionasrelatedtocleanabilityandthetypeofmaterialusedforconstruction.
Guidelines to evaluate cleanabilityThe American Meat Institute has es-tablished an Equipment Design TaskForce with the objective to minimizethe spread of Listeria in meat process-ing plants. This Task Force has es-tablished sanitary design principlesand criteria in consultation with equip-
mentmanufacturers, certifyingorgani-zations and government officials. Thefollowing10principlesofsanitarydesignhavebeendeveloped.
1. Cleanabletoamicrobiologicallevel:Food equipmentmust be constructed toensureeffectiveandefficientcleaningoverthelifeoftheequipment.Theequipmentshouldbedesignedastopreventbacterialingress,survival,growthandreproductiononbothproductandnon-productcontactsurfacesoftheequipment.
2. Madeofcompatiblematerials:Con-struction materials used for equipmentmust be completely compatiblewith theproduct,environment,cleaningandsani-tizingchemicalsandthemethodsofclean-ingandsanitation.
3. Accessible for inspection, mainte-nance,cleaningandsanitation:Allpartsoftheequipmentshallbereadilyaccessi-bleforinspection,maintenance,cleaningandsanitationwithouttheuseoftools.
4. Noproductorliquidcollection:Equip-mentshouldbeself-drainingtoassurethatliquid,whichcanharborandpromotethegrowthofbacteria,doesnotaccumulate,poolorcondenseontheequipment.

Kuchenmeister Ensures High Quality Standardswith Product Inspection Equipment
To achieve optimal production processes and a consistent, high quality product, Kuchenmeister
uses a range of product inspection equipment from METTLER TOLEDO, including dynamic
checkweighers and Safeline metal detection and X-ray inspection systems.
Kuchenmeister, a family-owned bakery,hasbeenproducingarangeofbakeryspe-cialitiesforover120years.ThecompanyaremarketleadersincakesandareoneofthelargestbakeriesinGermany,distribut-ingover500productsworldwide,undertheirownandretailerbrandnames.
