Pyramid tea bags and regular tea bags are the most popular tea variants used in various households and commercial spaces.

However, they vary in a few aspects, such as the following;

Material

Pyramid tea bags are made from a relatively strong material than regular tea bags.

The former is made using a nylon material that enables the tea leaves to expand and move around freely.

On the other hand, regular tea leaves are made from PET material, which is seemingly cheaper and easy to produce in mass.

Reliability

The nylon material reduces the chances of pyramid tea bags tearing or leaking, making them more reliable than regular tea bags.

PET material used for making regular tea bags can easily tear and leak, making this tea bag relatively unreliable.

Design Structure

The design of pyramid tea bags has additional space provided that allows the tea leaves to move around freely and fully expand.

As such, these tea bags infuse more flavors allowing tea manufacturers to incorporate large high-quality tea leaves in pyramid tea bags.

On the other hand, PET hardly allows tea leaves to expand, and this is likely to lead to a weaker flavor.

Quality

Pyramid bags are spacious hence allowing addition of quality additives to enhance the overall flavor of the tea bags.

Regular bags, on the other hand, have limited space thus commonly contain low-quality tea leaves broken into smaller pieces leading to a weaker aroma.

• 220V/2KW electric power rating
• Air consumption of 0.6m³ per minute
• Weighing range of 1-7g
• Dimension of 1200 x 920 x 2060 mm
• 2 sets of sealing and cutting devices
• Length of bags ranges from 50, 60, 70, and 80 mm

The main parts of this pyramid tea bag packing include the following;

• Hopper – This is an elongated funnel-shaped component designed for feeding tea leaves into the equipment for subsequent packaging process.
• Stainless Steel Frame – It is the structural component where all other parts of this machine are affixed as it ensures stability and efficiency during tea bag packaging.
• PLC Touchscreen – It displays various operations used during the packaging process. You can also use it to monitor the different pyramid tea bag packaging parameters.
• Pneumatic Control Unit – This component provides means to actuate valves often used in regulating airflow in this equipment’s pneumatic system.
• Control Keys – These are buttons used to activate different control parameters of the machine during the pyramid tea bag packaging process.
• Precision Optical Sensor – It measures the physical quantity of light and translates it into readable form to enhance tea bag filling accuracy.
• Feeding Conveyor – It is a panel that ensures movement of the packaged pyramid tea bag from one station to another.
• Universal Wheels – They are attached to the bottom of the machine to enable convenient movement from one point to another.
• Film Roll Holder – It is designed to hold and discharge pyramid tea bag packaging material into the machine for subsequent tea leaves’ loading.

• Servo-Motor – This refers to a rotary actuator, which enables accurate control of velocity, acceleration and angular position.

The functional mechanism of this equipment is quite straightforward and usually entails the following steps;

• This machine comes with a tea weigher or linear weigher, which fills the pyramid bags with tea leaves.

An electric tea weigher or any tea weight measurement device is used with the tea leaves filling hopper.

• The conveyor unit of this equipment transfers containers to the specific tea filling component. This component discharges the tea into available nylon sachets that are being created.

Hence, the sachets end up as the tea bags, which will handle the tea directly.

• The device responsible for internal nylon bag sealing and cutting seals and cuts the tea bags respectively and form into paper filter sachets resembling a pyramid.

Even so, some machines enable the design of tea bag adjustment to give rectangular bags.

• Next, bucket elevator links the pyramid tea bag packing equipment to the envelope tea bag packer.

The former machine has a foil roll stock with the nylon material it uses to create envelopes.

It contains an external bag where packaging of tea bags takes place for supplementary cleanliness.

• Then, the external foil bag forming device forms the external bags.

The devices for external bag cutting and sealing are then actuated to seal and cut external bags filled with tea bags.

It attains high accuracy through a device referred to as optoelectronic positioning unit.

The cutting device for external bag counts the quantity of tea bags, which are being packed in a single external bag.

• The pyramid tea bags are discharged through an output conveyor to allow extra packaging process.

When buying this machine, it is advisable to consider a few critical elements to ensure you meet your industrial packaging demands.

Such considerations include the following;

• Budget – Establish whether your business can sustain the procurement of the specific machine and ascertain its feasibility.

Also, determine whether you can obtain machine financing from investors or other financiers where applicable.

• Packaging Demands – Ensure you know the actual packaging requirements upfront before buying the machine.

Know the tea categories and the tea character to enable you to acquire a tea packaging machine that meets the specific requirements.

• Available Floor Space – The essence here is to ensure you buy a specific machine with dimensions that can fit your space.

Most automated pyramid tea bag packing machines are usually compact. However,  you need enough space for other processes like storage and operators’ area.

• Usability – Automatic pyramid tea bag packing machines often come with a human-machine interface making them quite user-friendly.

However, it’s important to ensure the HMI is clear and straightforward.

• Brand – The specific manufacturer or supplier you purchase from should be of good reputation, authentic, verifiable, and certified.

Determine the technical user support you attain from the vendor, detailed manuals, and after-sales support offered.

• Features – Ensure you look into the features and establish they can enable you to attain the packaging demands accordingly.

When purchasing this tea type of tea bag packaging equipment, it is vital to ensure it has certifications authenticating it has passed required quality tests.
