Abstract

This research presents the processing of fresh guava into guava juice product. to be kept for consumption and distribution in the local area It is an alternative career path that helps rural farmers earn more. and create additional careers for the family But farmers still lack the correct technology, tools and processing methods in each production process. Therefore, there was a problem of insufficient cleanliness, taking a lot of time, resulting in unacceptable quality and the production is low, the postharvest engineering research group has conducted research to find suitable guava juicer. This study is based on working principles of food processing equipment in general use. Come as a guideline to develop, improve and create prototypes. The original guava juicer was a grater roller squeezer. There is a guava-sized subsystem consisting of a sub-chamber with grated rollers and the waste water barrier system consists of a juice sieve chamber, a waste separation room, a spiral conveyer and a sweeper set. various parts that come in contact with the guava juice is made of stainless steel The power source uses a 1-horsepower electric motor, a single-phase electrical system, a voltage of 220 volts. The machine has the ability to block water at a rate of 250 kg / hour. The juice obtained must be filtered out again with a centrifugal bag filter capable of filtering water at a rate of 50 liters/hour. The prototype guava juice machine costs 40,000 baht, and the centrifugal filter bag costs 5,000 baht. With just one such machine, each of these machines can produce 28,000 liters of guava juice/year (112,000 bottles a year), able to get a return in 0.08 years, with an average processing cost of 4.48 baht/bottle, which is appropriate in engineering economics. In investment, use a ready-to-drink guava juice machine. Fresh guava ingredients are available throughout the year and have 200 business days/year.
