Hops are used primarily as a bittering, flavouring, and stability agent in beer, to which, in addition to bitterness, they impart floral, fruity, or citrus flavours and aromas. Therefore, what we see most is the use of hops in beer. Hop pelletizing equipment is indispensable for producing hop pellets, that is, hop pelletizer.
Hops pellet making machine is base on hops as the main raw materials to making the biomass pellets. Also the pellet machine can pellet other materials into pellets, like corn stalk,wheat straw,rice straw,sawdust and so on after they are grinding. With the development of biomass pellet production, more and more Hops are available as raw materials for biomass pellet making. The hops pellet making machine is also more popular in biomass pellet production.

Pellets sink and dissolve, creating a clear surface area advantage and, in turn, utilization advantage. This utilization advantage is further heightened by lupulin glands that have been ruptured by the milling process; making the isomerization of alpha acids easier. Both, the surface area and alpha acid availability translate to a 10 to 15 percent increase in utilization over whole hops.
Though, technically this increase is not high enough for a brewer to change the hop amount in a recipe when going between the two forms, if you find that there is a harsh quality to a beer after switching to pellet hops, it may be worth trying the same recipe with a slightly downsized dose.
The outer shell of lupulin resin helps protect the pellets from oxidation giving them a longer storage life, with less chance of damage to quality. Pellet hops are also easier to measure out, work with, and take up less storage space than whole hops. These factors together, actually produce another advantage to the home brewer; the availability of more hop varieties.
Most of the disadvantages of pellets stem from their advantages. They sink and dissolve, meaning they create “sludge” on the bottom of your brew kettle or fermenter. If in the fermenter it can impede siphoning. Also, if a dry hop addition is added too early it’s possible that dead yeast cells may cover the hop powder, limiting wort contact.
The extra processing due to milling can negatively affect the aromatic quality. Whole lupulin glands allow a slow release of essential oils giving time for some oxidation of humulene and other hydrocarbons. The ruptured glands of pellets means a loss of a major portion of these compounds long before their oxidative states have a chance to form.
