Abstract: Offering different technical solutions in butter production line facilitates the whole process of manufacturing. Butter production line contains a lot of machines which are connected to each other in one complex system. Depending on the capacity of production, machines are selected to meet the required amount of butter. The selection and quality of the machines that will be used in the butter production line depends on the funds that are available from manufacturing company. They need to select appropriate machinery and additional equipment from reputable manufacturers, just to ensure safe implementation of the process. Manufacturing companies need to use machines with optimal technical characteristics (production capacity, rpm, electricity consumption, their weight, automatic work, etc.)We've offered different technical solutions in butter production line. Manufacturing companies can choose the right machines for their production line, machines that meet their needs.
Key words: machines, butter production, technical solutions;
Introduction: Milk is the basis for production of all dairy products (various types of cheese, butter, various liquid milk drinks etc.).(Pesilski, 2004).Butter is one of the main dairy products. In the past, the production of butter was more developed in the northern regions, but at the beginning of 20-th century the terms for its production were different, so that the production of butter spread beyond wet and cold climates. Crucial role having played two moments: finding separator and cooling machines, significantly improved transport links. In Europe, butter was mentioned as a diary product in 13-th century. In northern European countries in 15-th century, butter production was more developed, and took important place in internal and external trade. (Tratnik, 1998). With the further development of trade and industry, its growing importance as a living product was more expressed in the 19th century and 20th century. Butter has had a major role in human nutrition, and began to develop as a individual independent industrial branch.(Ka-pac Parkacheva, 1986)
Material and methods: By using descriptive method was made comparative analysis of various machines used in the technological line for the production of butter.
Results and discussion: During the process of butter production, the milk is held in milk storage tanks. There are different storage milk tanks. Depending on the production capacity of butter are used milk storage tanks with different. We've offered three models of storage milk tanks with different capacity: 300 liters, 1000-5000 liters and 10000-15000 liters. Smaller milk diary companies use smaller milk storage tanks (example milk storage tank with capacity of 300 liters). Another smaller milk diary companies use bigger milk storage tanks (example milk storage tank
with capacity of 1000-5000 liters). Big diary companies, who produce large amount of butter, use milk storage tanks with bigger capacity (example milk storage tank with capacity of 10000-15000 liters). All milk storage tanks have identical function (they collect milk and proceed it to other parts of the processing line for butter production), they are all made of stainless steel. The only
difference between milk storage tanks is their capacity.

The pasteurizer in butter production line has two main tasks: pasteurization of skim milk, pasteurization of sour cream. For these procedures we usually use plate pasteurizer. We've offered different models of plate pasteurizers (MGT process): T4: 300l/h Electric Heating System;T4: 500l/h EHS;T4: 1000l/h EHS; H17: 2500l/h Boiler Heating System; H17: 5000l/h BHS;H17: 50001/hBHS;
First three models of plate pasteurizers can reach maximum temperature of 110oC for pasteurization process. The have low cost for supply and installation. They also have flexible construction. The projection of this pasteurizers is based on the most stringent requirements for environmental protection. They are all made of stainless steel (SS316).

Other three models of plate pasteurizers work on the principle HTST (briefly attains the required temperature) thereby they perform their function faster than other models of pasteurizers. They are made of stainless steel, they have 90% thermal regeneration, automatic control panel with touch screen, digital control of the temperature of pasteurization. There are widely used in major diary facilities.We've offered different types of cream separators, and made comparative analysis between them.
Separator functions: Two-stage of milk separation: skimmed milk and cream. Cream separator type RS-07 is made of stainless steel, it has capacity of 601/h and it's hand powered, 35kg.

Cream separator Type UFL-005F is made of stainless steel, it has capacity of 1000l/h, it has electricity consumption of 1,5kW/h and weight of 198 kg. These two models of separators are used in smaller processing facilities. Hand powered separator can be used when we want to save electricity.
Larger processing facilities used another models of separators just to meet the required ca-
parity of butter production. Manufacturer KISAN has offered some models of cream separators which have the following characteristics: they are all made of stainless steel, but have different capacity (Model typel- 2000l/h, Model type2- 3000l/h, Model type3-5000l/h). When the process of milk separation is completed, the percent of milk fats in skimmed milk is 0,05%., They have electricity consumption of 2,5kW/h.
Butter churn
Smaller milk diary companies can use butter churn Type Bimal with these characteristics:
capacity of 20-601/h, handpowered, made of stainless steel AISI 304SS.

tavron
The same manufacturer offers butter churn that runs on electricity, and has the following characteristics: capacity of 20-120l/h, made of stainless steel AISI 204SS, electricity consumption 1kw/h. Larger processing capacities can use butter churn Type TAVRON, which has capacity 50-600l/h, made of stainless steel, runs on electricity, control panel and CIP-System.
Machines for continuous butter production
We've offered three different machines for continuous butter production from the same manufacturer.
The first model Type Westfalia Buc 800, has capacity 800 kg/h, is made of stainless steel, has two cylinders, it has electricity consumption of 17 kw/h.

1500
The second model Type Westfalia Buc 1000, has capacity of 1000 kg/h, it is made of stainless steel, electricity consumption of 17 kW/h. The third model Type Westfalia Buc 1500, has capacity of 1500 kg/h, it is made of stainless steel, electricity consumption of 17 kW/h.
Machines for butter packing
We've offered three different models of machines for butter packaging. The first model Type DPF-80, is used for butter packaging in small packages (10 g), the process is fully automatic, it has capacity of 3000 pcs/h. The second model Type Benil 8380 is used for butter packaging in bigger packages (20-25 kg), it has capacity of 151 boxes for one hour, the dimensions of the boxes are following: 380x253x228, electricity consumption 1,5 kW/h and weight of 305 kg. The third model Type DPP-250Y is completely automatic machine for butter packaging. It is made of
stainless steel, it has system for process control, alarm system, the dimensions of butter package is 250x150x30, it has electricity consumption of 5,7kW/h and weight of 1500 kg.
Pic.10 Machine for butter packaging Type DPP-250Y Conclusion: Butter is high quality product which contains high percent of fats. For standardization and quality in butter production line, it needs fulfillment of the following factors:Usage of quality raw materials (high quality milk); Usage of appropriate technological process with continuous observed parameters; Selection of appropriate machinery and equipment from reputable manufacturers to ensure safe implementation of this process, made of stainless steel; Usage of machines with optimal technical characteristics (production capacity, rpm, electricity consumption, their weight, automatic work etc.); Proper selection of machines because of their impact on the economic indicators of the installation; Compliance with food safety law; HACCP implementation; By offering different machines in butter production line, we can choose the appropriate machinery and additional equipment just to ensure safe implementation of the process, machines with optimal technical characteristics that meet the needs of manufacturer companies References
