Process for preparing plant extract wherein natural gas is utilized to achieve uniform heating for accelerating the rate of extraction and to improve the environmental awareness
The present invention relates to a preparation process of plant extract, which mainly comprises the following steps: taking and washing at least one plant material (which may be herbal leaves or Makino bamboo leaves) cutting the washed plant material and adding fluids after cutting using natural gas to carry out distillation at a high temperature of 95 DEG C for 150 minutes to produce a plant extract then the plant extract is cooled after cooling, the precipitated impurities can be filtered finally the filtered plant extract is packaged to complete the preparation process of the herbal tea of this invention. Accordingly, natural gas is utilized to achieve uniform heating for accelerating the rate of extraction and to enhance the environmental awareness without chopping down the trees, and the herbal tea tastes no bitterness.本發明為有關一種植物萃取液之製程,主要可取至少一種植物原料(可為青草葉或桂竹葉)進行清洗工作,再將清洗過後的植物原料進行切塊,並於切塊後加入流體再利用瓦斯於95度c以上之高溫進行蒸餾,而持續蒸餾150分鐘以內,以產生出植物萃取液,爾後再對植物萃取液進行冷卻工作,當冷卻完畢後即可將沉澱的雜質進行過濾,最後再將過濾後的植物萃取液進行包裝,即完成本發明之青草茶製程,藉此,透過瓦斯進行平均火力加熱得以加速其萃取之速度,並更可以提高環保意識而無須砍伐樹木,且飲用時完全無苦澀感。A‧‧‧清洗B‧‧‧切塊C‧‧‧蒸餾D‧‧‧冷卻E‧‧‧過濾F‧‧‧包裝
