1. Coffee production line - basic production process Reception of raw coffee beans - selection and storage of raw coffee beans - quantification, preparation for mixing and baking - crushing processing - extraction processing and aroma recovery (exhaust gas recovery) - concentration treatment - spray treatment - agglomeration treatment - fragrance additives - packaging processing - Instant coffee for sale - domestic sales and exports. 2, coffee production line - basic coffee processing Raw coffee is washed, baked and smashed. The raw coffee is washed and picked and transferred to the roaster. Coffee roast, at a temperature of about 180 ° ~ 200 ° C in 250 kg per batch, about 15 '. After baking, it is collected and stored, then pulverized, and then subjected to instant treatment. 3, coffee production line - extraction Extracting coffee solution with -8 cylindrical containers It is recommended to include an alternate extraction cylinder to facilitate continuous operation. 24 hours a day and 7 days a week. Calculate the appropriate volume to achieve better baking work and extract coffee, pour hot water around 190 degrees Celsius, more to be consumed and move up, through each cylinder with a small amount of coffee grounds, water This flow passes through each cylinder continuously. This extraction, carried out continuously, fills the gap between the new cylindrical coffee grounds. At the same time, the slag is wetted. Better gas transfer upwards and outwards. The coffee extract leaves this freshly baked and smashed column as a juice. The concentration of coffee solute ranges from 10% to 30% Hot water and boiled coffee grounds continue to flow into the column. The extract extracted from the cylinder of freshly roasted and ground coffee was intermittently withdrawn. During this process (when the extract enters a special cylinder of freshly roasted and ground coffee and the condensate is released from the coffee cylinder and has been detached from the water) the coffee has become wet, extracted, and soluble has been hydrolyzed. . For seven or eight cylindrical systems, it will take 3 hours. A cylinder leaves the water effluent, checks, feeds and feeds. 4, coffee production line - fragrance recycling There are two basic steps involved: A small portion was separated prior to the extraction process and added prior to the addition. The aroma portion is separated after the evaporation process to make the product a good beverage. In any case, it must be noted that there are two options for the customer to choose. Improve the operation of the PETRONCINI system to recover the scent and taste of the entire extraction before the evaporation system is concentrated. Advantages: Acidity hydrolysis of natural agricultural products has been removed during evaporation, in the third extraction, and the total of flavor and taste is recombined. Previous separations, such as using our system, guarantee the best quality and have a very good taste. If you choose this recycling system, you don't have to separate the fragrance part from the hydrolysis part during the extraction process, so the fragrance recovery system is superfluous. An additional system for the most typical low temperature solids and high quality aromas is included in this extraction system (ALILT system) 5, coffee production line - evaporation To reduce the cost of spray drying, we concentrated 12-15% solids extraction concentration up to 50%. Of course, if you want a low concentration, it is okay to design a 35% solids concentration chamber. Usually unfavorable, the fragrance will be lost during evaporation, but with our fragrance recovery system, 100% excludes this. 6, coffee production line - spray drying Spray drying or atomization is the most common, and it is effective and economical to obtain instant coffee. In short, it guarantees the high quality and good taste of the product. During this process, a high-structure dryer with medium pressure nozzles and dry air are used in parallel. Heating compressed air relies on a system that is directly powered by gas or a system that relies on steam or liquid fuel. The drying temperature is very important, in order to keep the fragrance unchanged, the temperature must be lower. The product consisting of the instant powder is dried, and the hollow small sphere is made into particles of about 100 ÷ 300 μm. A CO2 injection system is needed to reduce bulk density.
