Rotary Drying is a fast and effective method of drying that requires a relatively small space for large volumes. Here is a brief description of how rotary drying works:

Wet product is brought into direct contact with a hot air stream that is generated from any number of fuel sources. The wet product and hot air are drawn into a rotating dryer drum. The hot air stream dries and conveys the product in a concurrent process. The drum is equipped with internal longitudinal lifting flights that repeatedly drops the product into the axial air stream. As the product dries inside the drum it advances towards the collection system for the dried product.

The desired outlet moisture of the product is obtained by controlling the drum outlet air temperature, modulating the fuel control system as required. The heat source is modulated on the infeed side of the dryer. As the amount of product and moisture in the drum increase, the inlet temperature increases accordingly to satisfy the heat needed to dry the product effectively.

At the discharge end of the drum, the dried product is conveyed into cyclones where the product is separated from the airstream and discharged.

After the cyclones, the airstream is ducted to an induced draft fan. The fan creates a suction on the system that has two functions: to pull the heat from the burner through the drum and to advance the product in the rotary drum. duct dries inside the drum it advances towards the collection system for the dried product.

Illinois, Wisconsin universities team up to test different hemp varieties with farmers’ help

HEMP INDUSTRY DAILY
July 15, 2020

The University of Illinois and the University of Wisconsin are recruiting Midwestern farmers to plant and test different varieties of hemp this year in exchange for discounted cannabinoid sampling.

Project participants must agree to at least two sampling dates per plant variety for collection into the Midwestern Hemp Database. The University of Illinois Extension says that as a new crop to the Midwest, “best management practices (BMPs) and varietal performance of industrial hemp have yet to be determined.”

The U.S. exported 572,499.8 metric tons of wood pellets in May, up from 553,885.4 metric tons exported during the same month of last year, but down from the 595,166.2 metric tons exported in April, according to data released by the USDA Foreign Agricultural Service on July 2.

The U.S. exported wood pellets to approximately 17 countries during May. The U.K. was the top destination with 399,586.5 metric tons, followed by Belgium-Luxembourg with 114,511.1 tons and the Netherlands with 33,145.1 metric tons.

Combustible wood dust in confined storage could present a risk of fire and explosion if it’s not managed effectively. The Wood Pellet Association of Canada (WPAC) has developed tools to improve safety and lower the risk when working around wood fibre storage.

In 2017, the Wood Pellet Association of Canada (WPAC)’s Safety Committee, in collaboration with the BC Forest Safety Council (BCFSC), the Manufacturing Advisory Group and WorkSafeBC, established a Working Group to lead the process on developing best practices for combustible dust management in wood fibre storage. This collaboration resulted in the formation of the Wood Fibre Storage Working Group (WFSWG), with the overall objective of improving safety within the wood manufacturing sector by eliminating injuries and fatalities.

Adding hemp to your crop rotation doesn’t involve as many regulatory hoops as it used to. With shorter varieties that make residue management easier and rapidly growing markets, especially for organic hemp, there seems to be a lot of potential value in this specialty crop.

Most hemp grown in Western Canada is used for human consumption, although there is renewed interest in hemp fibre, and if a planned decortication plant in Alberta goes ahead, it could provide future opportunities for the straw by-product.

The shortage of medical grade masks worldwide has hobbled health care professionals responding to the novel coronavirus — highlighting the need for improving supply lines and manufacturing more masks locally.

Researchers in the Bioproducts Institute at the University of British Columbia (UBC) have stepped up to the challenge, designing what could be the very first N95 mask that can be sourced and made entirely in Canada. It’s also possibly the world’s first fully compostable and biodegradable medical mask.

The U.S. Forest Service on April 16 announced it is awarding a total of $7.62 million to 35 projects as part of the agency’s Wood Innovations Grant Program. Eight of those projects focus on renewable energy, while the remaining 27 focus on expanding markets for wood products.

Countering arable land degradation: The waste that woke the soil

Countering arable land degradation: The waste that woke the soil

Soil is a natural resource that we often overlook and abuse just because of its supposed abundance. Some call it "dirt" and many times we attribute to stains and things we should rid ourselves of in the name of cleanliness. I choose to call it a "wonder" because on it we grow our food; it even covers up the dead. Just because it doesn't scream in pain when we step on it doesn't mean it isn't alive.
