Ricola’s instant herbal teas are very popular with consumers. In order for the teas to be able to unfold their full soothing effect consistently, they are produced with the help of a special method that ensures a consistently high fraction of active ingredients and flavors. Part of this method involves milling processes with the MF series of oscillating sieve mills from Frewitt.
The oscillating sieve mills of the MF series were originally developed for the gentle milling of heat sensitive products in the pharmaceutical industry. Later these mills acquired a permanent place in the food production industry as well.
Depending on the respective application, the user can select between 27 and 400 rotor oscillations per minute. This operating principle gives rise to numerous advantages: The milling process generates only a minimal amount of heat. The result of this gentle process is products with a very uniform grain size distribution and minimal fine particle fraction. Grain sizes of between 50 mm and 250 ìm are achievable / 100 g/h for laboratory applications to 4 t/h for industrial use.

Producing instant teas

Ricola has been using MF sieve mills for many years. The minimal fine particle fraction as well as the sturdy construction and low maintenance aspect of the mills were the decisive factors for this renowned Swiss company. The company uses the mills in the production of instant herbal teas. A special production method ensures a consistently high proportion of active ingredients and flavors in the teas. That is important, as consumers should be able to count on the soothing effect of the teas.
Milling processes play a key role in instant tea production. Ricola places particular value on low maintenance mills that produce a homogeneous grain size distribution with a minimal fine particle fraction. And it is precisely these requirements that the MF series oscillating sieve mills fulfill completely.
