Various types of herbal teas such as roses, chrysanthemums, and hibiscus have delicate raw materials, light and fragile petals, easily oxidized colors, and natural drying and storage can easily breed mold and bacteria, hide insect eggs, and lead to problems such as mold growth in finished products, insect infestation during storage, and poor quality inspection.
By using microwave technology, the sterilization, insecticidal egg production, and fragrance enhancement processes of flower tea can be completed in one stop, achieving fully automatic continuous production line production without damaging the appearance and internal quality of flower tea, making it the preferred process for deep processing of flower tea.
The equipment is equipped with variable-frequency controllable conveyor belt, which can connect with the whole production line of flower tea sorting and packaging to realize the closed-loop continuous operation of raw material feeding, disinfection and sterilization and deodorization, and finished product discharging, without the need for manual batch transfer, and reduce the damage and secondary pollution of flower petals. The equipment can flexibly adjust power and transmission speed according to different flower shapes and moisture contents, and is suitable for processing multiple categories of bulk flower tea, combination flower tea, and packaged flower tea. It has high efficiency and fast processing speed, and is suitable for large-scale order production of enterprises, effectively reducing labor production costs.
Different from the traditional external heating baking, the microwave can complete the disinfection and sterilization of scented tea from inside to outside in the low temperature state by relying on the penetrating physical thermal effect, and avoid high temperature damage from the root. The processing process will not squeeze or bake the petals, preserving the shape of the flower buds completely and eliminating problems such as burnt edges, broken petals, and deformation; Simultaneously inhibiting the oxidase activity of flowers and plants, locking in the original bright color of flowers, avoiding browning and yellowing. After brewing, the flowers stretch naturally and the appearance is intact.
Relying on the dual effects of thermal and non thermal biological effects, microwaves can penetrate the gaps between flower stamens and petals, killing hidden insect eggs and pathogenic bacteria in deep layers. The sterilization and egg killing rate is high, effectively solving the problem of insect infestation and mold growth in the later storage of flower tea. Pure physical processing has no residual chemicals or preservatives, which meets food safety production standards and is suitable for compliant processing of health preserving flower tea.
