70 results about "Instant tea" patented technology

Instant tea is a powder in which water is added, in order to reconstitute it into a cup of tea. The earliest form of instant tea was developed in the United Kingdom in 1885. A patent was granted for a paste made of concentrated tea extract, sugar, and evaporated milk, which became tea when hot water was added. However, no notable developments were made until spray drying technology allowed for drying the tea concentrates at a temperature which did not damage the flavors of the product.

An aseptic packaging machine for instant tea

This invention relates to the field of food packaging technology and discloses an aseptic packaging machine for instant tea, including a packaging table, a discharging component, a folding component, a first heat-sealing component, a flaring component, a feeding component, a grooving component, and a second heat-sealing component. This invention first uses the discharging component, folding component, and first heat-sealing component to vertically heat-seal the packaging film. Then, the flaring component and feeding component complete the bagging of tea powder. Next, the grooving component and second heat-sealing component simultaneously expel air from the packaging bag, grooving the bag and heat-sealing the top. The entire process requires no manual operation, thus avoiding contamination from manual bagging. Furthermore, by squeezing out as much gas as possible from the packaging bag before sealing, fungal growth is prevented. This reduces the difficulty of sterilization in the production workshop while achieving fully automated production.
