Custom Processing &
Steam Treatment
Advanced steam treatment and custom processing for dehydrated spices and botanical ingredients in Nicaragua, using hot saturated steam, multi-stage vacuum, controlled drying and final cooling for international B2B ingredient programs.
A Stronger Ingredient Supply Program
Doselva combines specialized thermal treatment with ingredient handling, controlled drying, traceability and buyer preparation. The result is a more complete processing solution for international B2B spice and botanical ingredient programs.
Controlled Thermal Processing for Global Ingredient Markets
Doselva uses an automated thermal-treatment system designed for dehydrated spices and botanical ingredients. The equipment combines hot, moist saturated steam with multi-stage vacuum technology to support heat transfer, microbiological control, controlled drying and moisture management throughout the treatment cycle.
Why Steam + Vacuum Instead of Steam Alone?
Alternating vacuum and saturated-steam cycles help remove residual air from the chamber, support steam penetration and create more controlled thermal conditions through the product.
Six Controlled Stages
Doselva’s steam treatment process for dehydrated spices and botanical ingredients integrates chamber preparation, multi-stage vacuum, saturated steam, thermal treatment, controlled drying and final cooling in one coordinated sequence.
The chamber is preheated before treatment begins.
Vacuum cycles help remove residual air and can reach below 30 mbar.
Hot, moist saturated steam is introduced into the chamber.
Alternating cycles support controlled heat transfer through the product.
Chamber-wall heating supports drying and moisture management.
Cold-water circulation reduces product temperature below 40°C.
How Doselva’s Steam Treatment Process Works
Doselva provides advanced steam treatment for dehydrated spices and botanical ingredients in Nicaragua using multi-stage vacuum, hot saturated steam, controlled heat transfer, drying and final cooling. The process is designed to support microbiological control, moisture management and consistent processing for international B2B ingredient programs.
Vacuum cycles help remove residual air from the chamber and can reach pressures below 30 mbar, preparing the treatment environment before steam injection.
Hot, moist saturated steam is introduced into the chamber to support controlled thermal treatment of dehydrated spices and botanical ingredients.
Alternating vacuum and steam cycles support heat transfer through the product under controlled processing conditions.
After thermal treatment, chamber-wall heating supports drying and moisture management before the cooling stage.
Cold-water circulation supports controlled cooling, with the described process targeting product temperatures below 40°C.
Technical Parameters for Controlled Spice Processing
Doselva’s steam treatment capability in Nicaragua combines multi-stage vacuum, validated microbiological reduction and controlled cooling to support dehydrated spice and botanical ingredient processing for international buyers.
Multi-Stage Vacuum Capability
Vacuum stages support residual-air removal before and during steam treatment, helping create controlled conditions for heat transfer through dehydrated spices and botanical ingredients.
Validated Microbiological Reduction
The evaluated steam treatment process demonstrated a minimum 5 log₁₀ microbiological reduction under the validated treatment conditions.
Controlled Cooling Target
After thermal treatment and drying, cold-water circulation supports final cooling to the described target temperature below 40°C.

Steam Treatment Questions
What is steam treatment for spices and botanical ingredients?
It is a controlled thermal process using hot saturated steam. Doselva’s system combines steam with multi-stage vacuum, drying and cooling stages for approved dehydrated ingredients.
Why is vacuum used before and during steam injection?
Vacuum cycles help remove residual air from the chamber and support steam penetration and controlled heat transfer.
What does <30 mbar mean?
The system is capable of reaching pressures below 30 mbar during the multi-stage vacuum sequence.
What does a 5-log reduction mean?
A 5-log reduction represents a 100,000-fold, or 99.999%, reduction in the evaluated surrogate microorganism population under validated conditions.
Can different ingredients require different processing parameters?
Yes. Processing should be evaluated according to ingredient, format, microbiological objective and buyer requirements.
