BPS and BPF have been detected in many everyday products, such as personal care products (e.g., body wash, hair care products, makeup, lotions, toothpaste), paper products (e.g., currency, flyers, tickets, mailing envelopes, airplane boarding passes), and food (e.g., dairy products, meat and meat products, vegetables, canned foods, cereals). BPS, BPF, and BPA have been detected in indoor dust at the following concentrations: BPS, 0.34 μg/g; BPF, 0.054 μg/g; BPA, 1.33 μg/g . BPS and BPF have also been detected in surface water, sediment, and sewage effluent, generally at lower concentrations than BPA, but in the same order of magnitude . In humans, BPS and BPF have been detected in urine at concentrations and frequencies comparable to BPA. In urine samples from 100 American, nonoccupationally exposed adults, found BPF in 55% of samples at concentrations up to 212 ng/mL, and BPS in 78% of samples at concentrations up to 12.3 ng/mL. BPA was found in 95% of the samples, with concentrations up to 37.7 ng/mL.

Working Principle:
The boiling point of the water in the materials will be reduced at vacuum, which is utilized by the rake vacuum dryer. This equipment is indirectly heated by steam jacket and the moisture is evaporated and removed immediately. In the shell of the dryer, rake teeth is driven by transmission shaft.  And there is a certain angle designed between rake teeth end and the axis. Materials move forward along the axis by the clockwise and counter clockwise rotation of the main shaft. 
Loading Coefficient: 0.4-0.6
Material: Stainless Steel, Ti-alloy, Hastelloy etc.
Features:
