Non-Thermal Drying — SpiroFlo
Industries serviced include minerals processing, agricultural, recycling, ecological, and energy markets. In drying applications, the EcoVeyor™ mechanically dewaters solids by coupling the oscillating spiral of its proprietary flow with either no or low-grade heat (150° F—typically found on-site).
Thermal Drying - an overview | ScienceDirect Topics
Drying involves thermally removing volatile substances (e.g., moisture) to yield a solid product. Mechanical methods for separating a liquid from a solid are not considered drying. In this chapter, we deal with thermal drying only. When a wet solid is subjected to thermal drying, two processes occur simultaneously: 1.
Thermical drying - VCM vzw
The objectives of thermal drying of manure are similar to those of biothermal drying, but the difference is that the heat is not produced by micro-organisms but from an external heat source. The goal of thermal drying is to reduce the volume and volume of the manure. Germ reduction also takes place at a certain level during drying.
