Superheated Steam - an overview | ScienceDirect Topics
Superheated steam drying is a promising drying technique in processing industry as it also offers additional advantages such as low energy consumption and improved food hygiene. As the operating temperature of superheated steam drying is typically high, this drying technique permits pasteurization, sterilization, and deodorization of food products.
Mechanism of the rapid generation of superheated and saturated …
2024年12月1日 · The final temperature of the generated steam increased with the increasing heating power and that the time required for the steam temperature to exceed the saturation temperature and attain the superheated state decreased significantly, i.e., only ∼ 1.9 s was required to generate SHS at 300 °C from subcooled water at 25 °C using an input ...
Superheated steam drying - ScienceDirect
2023年1月1日 · Superheated steam drying (SSD) is simply a kind of convective drying of materials by utilizing steam-heated beyond its boiling point instead of air, which is in direct contact with the material. This chapter discusses the fundamentals of SSD, different methods of SSD application, and mathematical models developed for SSD applications.
Effect of superheated steam drying on properties of foodstuffs and ...
2016年4月1日 · LPSSD — low pressure superheated steam drying, SSD — superheated steam drying, VD — vacuum drying, HAD — hot air drying, FIR — far infra-red, redness (a*), yellowness (b*). Drying of potato slices was carried by SSD (170–240 °C) and HAD (170–240 °C) by Iyota et al. (2001) and changes in color were observed.
The flow and heat transfer characteristics of superheated steam in ...
2017年12月1日 · A.Z. Xu, L.X. Mu, Z.F. Fan, L. Zhao, New findings on heatloss of superheated steam transmitted along the wellbore and heating enhancement in heavy oil reservoirs, in: The International Petroleum Technology Conference Held in Beijing, China, 26–28 March, 2013.
Superheated steam drying: Design aspects, energetic …
2016年7月1日 · A superheated steam vacuum drying trial was developed by Pang et al. [36], [37], [38] in order to dry a stack of wood, as illustrated in Fig. 13 (rearranged from Ref. [37]). The steam is heated to the wanted dry-bulb temperature by hot oil which can flow using a pump through heating coils above the stack of wood.
Thermodynamic properties of superheated and supercritical steam ...
2001年4月1日 · Equations for superheated steam-property calculations from Ref. [5] are given here along with the associated constants. (A1) F v = RT P −b 1 exp −b 2 T + 1 10 P b 3 − exp ∑ n=0 2 A n T n exp T s −T m where,
The contribution of superheated steam treatment of wheat flour …
2021年4月1日 · The effect of superheated steam treatment on the physicochemical properties of wheat flour and quality characteristics of cake were investigated. Superheated steam treatment significantly increased the swelling power, viscosities and gelatinization temperature, but reduced the gelatinization enthalpy (p < 0.05), compared with native wheat flour.
Fast torrefaction of large biomass particles by superheated steam ...
2022年2月1日 · Superheated steam (SHS) as the carrier gas and sole heat source was proposed to heat biomass rapidly and evenly while generating intensively torrefied biomass. This work revealed the potential of SHS torrefaction to upgrade large wood particles ( Φ = 30 mm, H = 60 mm), to improve the feedstock suitability and expand products diversity in ...
The mass and heat transfer characteristics of superheated steam …
2017年7月1日 · Superheated steam is obtained by continuous heating of saturated steam, and it has brought a huge increase in oil recovery (Xu et al., 2013a, Xu et al., 2013b, Sun et al., 2017a). Moreover, non-condensing gases are proved by both laboratory and field tests to be effective in decreasing heavy oil viscosity, increasing heated radius, etc. ( Sun ...
